Shelling, looting in Sudan's capital as military factions battle for eighth week

Shelling hit western areas of Sudan's capital on Monday morning after rival military factions fought through the night, residents said, with reports of deepening lawlessness in Khartoum and in the western region of Darfur.

Iran to reopen diplomatic missions in Saudi Arabia this week -official

Iran will reopen its diplomatic missions in Saudi Arabia this week, the Iranian foreign ministry spokesman said on Monday, several months after Tehran and Riyadh agreed to end years of antagonism under a Chinese-brokered deal.

US Navy shows Chinese warship's 'unsafe interaction' near Taiwan

The U.S. Navy has released a video of what it called an "unsafe interaction" in the Taiwan Strait, in which a Chinese warship crossed in front of a U.S. destroyer in the sensitive waterway, a risky incident amid deteriorating Sino-U.S. ties.

UK's Sunak says his immigration plan is working, reducing numbers

British Prime Minister Rishi Sunak said on Monday his plan to stop migrants arriving in small boats had reduced crossings by 20%, an update he hopes will ease criticism from his party and in the country over immigration policy. Sunak, who is expected to lead his governing Conservative Party into a national election next year, has promised to "stop the boats" from crossing the English Channel as one of his five pledges after he was propelled to power in October last year.

Analysis-Crowded 2024 Republican race helps clear way for Trump's nomination

A growing number of contenders for the 2024 Republican presidential nomination could clear the way for a Donald Trump victory while throwing up roadblocks for his main rival Florida Governor Ron DeSantis, party members and strategists said. Republicans who fear Trump is too polarizing a figure to beat Democratic President Joe Biden in 2024 worry that if too many candidates jump into the party's contest, they will splinter the anti-Trump vote. That would allow the former president to clinch the nomination, just as he did in similar circumstances in 2016.
