He has strongly denied all allegations.

The Senate passed legislation Monday to reopen the government, bringing the longest shutdown in history closer to an end as a small group of Democrats ratified a deal with Republicans despite searing criticism from within their party.

President Donald Trump has signaled support for the bill, saying Monday that "we're going to be opening up our country very quickly."

Intensified fighting in central Sudan displaced some 2,000 people over the past three days, the U.N. migration agency said Monday, the latest in a war that has convulsed the country for more than two years and killed tens of thousands.

President Volodymyr Zelensky said Monday he wants to order 25 Patriot air defense systems from the United States, as Ukraine desperately tries to fend off relentless Russian aerial attacks that have brought rolling blackouts across Ukraine on the brink of winter.

Iran on Monday dismissed accusations by the United States that Tehran had attempted to kill the Israeli ambassador in Mexico, describing it as "absurd".

"We found this claim very ridiculous and absurd," said foreign ministry spokesman Esmaeil Baqaei during a weekly press briefing, adding that it was part of an attempt "to destroy Iran's friendly relations with other countries".

The United States and Israel on Friday accused Iran of trying to kill Israel's ambassador to Mexico, with Tehran rejecting the claim as a "big lie" and the Mexican government saying it was unaware of the plot.
