A migrant boat capsized off the coast of war-torn Yemen, leaving dozens of people, mostly from the Horn of Africa, missing, Yemeni officials said Monday.

Khalid al-Subeihi, an official with the Yemeni coast guard in the coastal city of Mocha, said the boat with 75 migrants on board capsised Sunday. He told The Associated Press that 26 people survived but at least 49 others remain missing. Another coast guard official, Lt. Co. Olwan al-Qameri, said the search was still underway Monday.
