LONDON - On his first full day in office, British Prime Minister Boris Johnson urged the European Union on Thursday to rethink its refusal to renegotiate the Brexit deal, setting himself on a twin-track collision course - with the bloc and his own lawmakers - over his vow to leave the EU by Oct. 31.

Johnson pledged to deliver Brexit and a "broader and bolder future," as he addressed a rowdy session of Parliament.

He was heckled loudly by an opposition determined to thwart him, with Labour Party leader Jeremy Corbyn dismissing Johnson's "arm-waving bluster." The EU's Brexit chief called Johnson's speech "combative" and his demands unacceptable.

Johnson, who took office on Wednesday, has less than 100 days to make good on his promise to deliver Brexit by Oct. 31. And Thursday's session of Parliament was the last before a six-week summer break.

Rejecting the Brexit withdrawal agreement negotiated by his predecessor Theresa May, Johnson insisted that while he wanted a deal, it could only happen if the EU budged, especially on an insurance policy for the Irish border that has been rejected by U.K. lawmakers.

"I hope that the EU will be equally ready and that they will rethink their current refusal to make any changes," he told Parliament during the 2 1/2-hour session. "If they do not, we will, of course, have to leave ... without an agreement."

Johnson later spoke to European Commission President Jean-Claude Juncker, who repeated the bloc's insistence that it will not renegotiate the agreement on departure terms that it struck with May.

Financier Jeffrey Epstein found injured in New York jail cell

NEW YORK - Wealthy financier Jeffrey Epstein was found on the floor of his jail cell with bruises on his neck early this week while awaiting trial on sex-trafficking charges, a person familiar with the matter said Thursday.

It was not clear whether the injuries were self-inflicted or from an assault, said the person, who was not authorized to discuss the case.

Epstein, 66, was treated and, according to the U.S. Bureau of Prisons, remains in custody at the federal Metropolitan Correctional Center in New York City. Jail records showed no indication he was taken to a hospital.

In a statement, the bureau gave no other details and would not comment on Epstein's condition. An Epstein lawyer had no immediate response.

It was not clear whether Epstein had any cellmates or was being held by himself.

N. Korea launched new type of short-range ballistic missiles

SEOUL, South Korea - North Korea fired a new type of short-range ballistic missile in two launches into the sea Thursday, South Korean officials said. They were North Korea's first weapons launches in more than two months.

The South's Joint Chiefs of Staff said the missiles were fired from near the eastern coastal town of Wonsan and flew about 270 miles and 430 miles respectively before landing off the country's east coast.

After a national security council meeting later Thursday, South Korea said the weapons North Korea launched were assessed as "a new kind of short-range ballistic missiles."

North Korea is banned by U.N. Security Council resolutions from engaging in any launch using ballistic technology.

Senate confirms Army general as next Joint Chiefs chairman

WASHINGTON - The Senate has voted 89-1 to confirm the Army's top officer, Gen. Mark Milley, to be the next chairman of the Joint Chiefs of Staff.

Milley will succeed Marine Gen. Joseph Dunford, whose term expires Oct. 1.

President Donald Trump announced last December that he'd picked Milley, who is a veteran of the wars in Iraq and Afghanistan.

The role of the chairman of the Joint Chiefs is to advise the president, the National Security Council and the defense secretary on a range of military matters.

The chairman does not command any military forces.

Milley's Senate-confirmed successor as Army chief of staff is Gen. James McConville, who is currently the Army vice chief of staff.

Giuliani: Got loan from Trump lawyer to pay taxes

NEW YORK - Rudy Giuliani said he was forced to borrow $100,000 from President Donald Trump's lawyer Marc Mukasey to pay his taxes after his wife tied up a joint bank account in their bitter divorce case.

Giuliani, who has been working as a lawyer for Trump free of charge, discussed the loan outside New York State Court in Manhattan after his wife's lawyer raised it at a hearing on Thursday.

Giuliani, 75, argues his income is drying up as the divorce case drags on, and that $800,000 he's made so far this year from other business ventures has been spent entirely on "marital expenses" tied to the couple's lavish lifestyle. Giuliani said he still owes $10,000 to Mukasey, who used to be his law partner.

"I had to borrow the money to pay taxes, because she was holding up the account," he said outside the courtroom.

Boats capsize off Libya coast; 150 migrants feared dead

CAIRO - Up to 150 Europe-bound migrants, including women and children, were missing and feared drowned on Thursday after the boats they were traveling in capsized in the Mediterranean Sea off Libya, the country's coast guard and the U.N. refugee agency said.

A top U.N. official described the shipwreck as "the worst Mediterranean tragedy" so far this year.

Ayoub Gassim, a spokesman for Libya's coast guard, said two boats carrying around 300 migrants capsized about 75 miles east of the capital, Tripoli.

Charlie Yaxley, a spokesman for the U.N. refugee agency, said 147 had been saved.

He added that so far this year, one person has died on the route from Libya to Europe for every six people that reached Europe shores.

Museum controversy: The vice chairman of New York's Whitney Museum of American Art resigned Thursday, days after eight artists asked to withdraw their work from a biennial exhibition over his ownership of a company that makes tear gas.

Warren Kanders, who had served on the Whitney's board of trustees since 2006, decried the "politicized and oftentimes toxic environment in which we find ourselves across all spheres of public discourse, including the art community," in a resignation letter. His company, Safariland Group, sells body armor for police, as well as tear gas, which critics say has been used on migrants at the U.S.-Mexico border as well as protesters elsewhere.
