Egypt scrambled to bring home 27 of its soldiers, who had been seized by one of Sudan’s warring parties. A Libyan warlord offered weapons to his favored side, U.S. officials said.

Diplomats from Africa, the Middle East and the West have appealed for a halt to the fighting that has reduced parts of the capital, Khartoum, to a smoking battlefield.
