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.

The International Organization for Migration said the displaced fled from several towns and villages in the area of Bara in North Kordofan province between Friday and Sunday.

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.

The Sudanese army intercepted drones fired overnight by its rival paramilitary group on two cities in Sudan's northeast, a military official said Friday.

The army official, who spoke on condition of anonymity to freely discuss the matter, said 15 drones targeted Atbara, a city north of the capital, in River Nile province. He confirmed that strikes caused no casualties. Local media reports said residents heard explosions.

For more than two years, Sudan's military and a powerful paramilitary force have torn the country apart in a war for power, both digging in against peace efforts even as atrocities mount and starvation spreads. One reason they can keep going is the support each reportedly gets from other nations looking for influence.

International alarm has grown since Oct. 26, when the paramilitary Rapid Support Forces seized the key city of el-Fasher in Sudan's Darfur region from the military and reportedly went on a rampage. Witnesses and aid groups say fighters have killed hundreds of civilians, and the fate of thousands more is unknown.

North Korea on Friday fired a suspected short-range ballistic missile toward its eastern waters, South Korea's military said, as Pyongyang steps up its testing activity while talks with Washington and Seoul remain stalled.

Students and others ran out in panic as gray smoke filled the mosque.
