EUROPE-MIGRANTS

NEW: Migrants flood Budapest rail station; no trains to the West

BUDAPEST, Hungary (AP) — Migrants have flooded into Budapest's Keleti train station as police leave, but the train operator says that there will be no trains going to Western Europe.

The rail company says its stance was due to "railway transport" security reasons.

Police shut down the Keleti terminal to migrants on Tuesday, preventing those with valid tickets but no travel documents from boarding trains to Austria and Germany, many migrants' preferred destination.

There was no immediate explanation from police or other authorities about Thursday's decisions.

Hungarian Prime Minister Viktor Orban is meeting European Union leaders on Thursday in Brussels.

OFFICER SHOT-MANHUNT

Heavy police presence near where officer shot

FOX LAKE, Ill. (AP) — A county sheriff's spokesman says authorities are responding to a report of two "suspicious subjects" in a northern Illinois town near where a police officer was fatally shot.

Lake County Sheriff's Sgt. Christopher Covelli says police officers with dogs are conducting systematic searches with air support Wednesday night in Volo.

Covelli says there's no evidence the scene is connected to the shooting of Lt. Charles Joseph Gliniewicz in nearby Fox Lake. But he says: "Given the circumstances, we're taking it very seriously."

Authorities say Gliniewicz, a 30-year police veteran, was shot Tuesday morning while pursuing three suspicious men. A manhunt for the subjects has been ongoing since then.

SAN FRANCISCO PIER SHOOTING

NEW: Judge may set murder trial in San Francisco pier shooting

SAN FRANCISCO (AP) — A San Francisco judge is deciding whether to schedule a murder trial for a Mexican national deported from the United States five times before shooting a young woman walking with her father.

A preliminary hearing on the matter is scheduled to resume Thursday in San Francisco. A judge could decide to schedule a murder trial as well.

Juan Francisco Lopez-Sanchez has pleaded not guilty to murder charges, though he admits to firing the shot that killed Kathryn Steinle on July 1. Lopez-Sanchez said the shooting was an accident.

He said he found a .40 caliber semiautomatic pistol under a bench on San Francisco's Pier 14. He said the gun accidentally fired when he picked it up.

OBAMA

Obama: Alaska's warming climate is wake-up call to US, world

KOTZEBUE, Alaska (AP) — President Barack Obama says Alaska's warming climate is a wake-up call to America and should be a wake-up call for the rest of the world, too.

Obama is in Kotzebue, Alaska, a small town north of the Arctic Circle.

On his way there Wednesday, he flew over the island village of Kivalina. The Alaska Native community of 400 is sinking into the ocean because of rising sea levels.

Obama says there aren't many other places in America going through what Kivalina's residents are facing. But he says there could be if America and the world don't act quickly enough against climate change.

The president has spent the past three days in Alaska to illustrate his message that climate change is here and must be dealt with.

GOP 2016-RNC PLEDGE

AP sources: GOP seeks pledge to avert Trump third-party run

WASHINGTON (AP) — The Republican National Committee has challenged every GOP presidential candidate to sign a pledge not to undertake a third-party bid in 2016 under any circumstances.

The challenge, confirmed by multiple campaigns on Wednesday, is aimed squarely at Donald Trump.

The billionaire businessman last month repeatedly threatened to launch a third-party bid should he fail to claim the Republican presidential nomination. Such a bid would make it all but impossible for the Republican Party to win the White House in 2016.

Republican National Committee Chairman Reince Priebus is set to meet privately with Trump in New York City on Thursday, where Trump is also scheduled to speak to reporters. The private meeting is confirmed by an RNC official who wasn't authorized to discuss Thursday's plan publicly.

CLINTON EMAIL-SUBPOENA

Worker who helped Clinton set up email server takes Fifth

WASHINGTON (AP) — A former State Department employee who helped Hillary Rodham Clinton set up her private email server says he will assert his Fifth Amendment right not to testify before the House committee on Benghazi.

Attorneys for Brian Pagliano sent the committee a letter Monday saying their client would not testify at a hearing planned for next week. The panel subpoenaed Pagliano last month.

The letter was first reported Wednesday by The Washington Post. The top Democrat on the Benghazi committee, Maryland congressman Elijah Cummings, confirmed the letter in a memo to fellow Democrats.

Cummings says he is not surprised that Pagliano would wish to take the Fifth given what Cummings calls the "wild and unsubstantiated accusations" against Clinton, the former secretary of state and current Democratic presidential candidate.

CHINA PARADE-TROOP CUT

China pledges to cut 300,000 troops from its massive army

BEIJING (AP) — Chinese President Xi Jinping has pledged a reduction of 300,000 troops from China's 2.3 million-member People's Liberation Army, amid rising personnel costs and growing technological capabilities that reduce the need for large numbers of troops.

The announcement Thursday at the start of a massive parade commemorating Japan's World War II defeat 70 years ago brings the military's headcount down to about 2 million.

Once known for its human wave tactics in conflicts such as the Korean War, the PLA is increasingly focused on high-tech weaponry and more focused missions.

As an example, the latest version of the PLA's mainstay bomber, the H-6K, requires just a three-person crew, half its former complement.

GUATEMALA-POLITICAL CRISIS

Guatemala prosecutor gets judge's order to detain president

GUATEMALA CITY (AP) — Guatemala's attorney general says a judge has granted her request for an order to detain President Otto Perez Molina in connection with a government corruption case that has thrown the country into turmoil.

Thelma Aldana says Judge Miquel Angel Galvez issued the order Wednesday afternoon on crimes of illicit association, fraud and receiving bribe money related to a widespread customs fraud ring in which the vice president has already been jailed and faces charges.

Aldana spoke late Wednesday to the Canal Antigua television station.

SKOREA-AMBASSADOR HURT

Seoul prosecutors seek 15-year term for US envoy attacker

SEOUL, South Korea (AP) — South Korean prosecutors have asked for a 15-year prison term for the man they say slashed the U.S. ambassador during a breakfast forum in March.

The Seoul Central District Court says prosecutors made the request Thursday at the end of the trial of Kim Ki-jong.

The court says it will issue a verdict Sept. 11.

Kim is facing charges of attempted murder, assaulting a foreign envoy and obstruction after police said he attacked Ambassador Mark Lippert with a knife, inflicting deep gashes on his face and arm. Lippert was treated at a Seoul hospital for five days.

Police said Kim told investigators he chose Lippert as a target to highlight his opposition to U.S.-South Korean military drills.

ROCK ON CAR

3 to be sentenced for rock throwing that injured teacher

LEWISBURG, Pa. (AP) — Three young men will soon learn their sentences for a rock-throwing incident last year that caused severe brain trauma to an Ohio schoolteacher as she passed through Pennsylvania in the dead of night.

A judge will decide Thursday what punishment is appropriate for Tyler Porter, Dylan Lahr and Keefer McGee for the July 2014 attack along Interstate 80 in central Pennsylvania.

The victim, middle school language arts teacher Sharon Budd, is expected to be in court for the proceeding.

A fourth man, Brett Lahr, already is serving 18 months to 20 years after pleading no contest to a conspiracy count.

The nearly 5-pound rock crashed through the front windshield of the car in which Budd was riding, striking her directly. She's already had seven surgeries.

OIL TRAINS-CITIES

Big cities scramble to be prepared for an oil train disaster

PHILADELPHIA (AP) — An Associated Press survey of nearly a dozen big cities reveals emergency planning for crude oil trains remains a work in progress.

The 100-car trains are loaded with crude oil from the Upper Midwest and rumble past schools, homes and businesses.

Cities around the country are scrambling to formulate emergency plans and train firefighters amid the latest safety threat: a fiftyfold increase in crude shipments that critics say has put millions of people living or working near the tracks at heightened risk of derailment, fire and explosion.

The mile-long trains from North Dakota carry around 3 million gallons of crude. Federal officials say a severe accident in a city could kill more than 200 people and cause $6 billion in damage.

The trains have become a common sight in places like Philadelphia, Chicago and Seattle.

SAT SCORES

SAT scores slip slightly as more students take test

WASHINGTON (AP) — Student performance on the SAT college entrance exam is showing no improvement, continuing a mostly downward trend over the last five years.

The College Board says in a report that a record number of students took the exam.

The report says the Class of 2015 scored an average 495 in reading, down from 497 the previous year.

The average score for math was 511, down from 513. Writing scores dropped three points, to 484 from 487. The top score in each category is 800.

The College Board, which administers the test, says only 42 percent of test-takers met the benchmark for indicating readiness for college-level work or career-training programs

About 1.7 million members of the Class of 2015 took the exam, up from 1.67 million for the 2014 class.
