In the Gulf of Aden, at least 49 people have drowned, and 140 others are missing, after a boat carrying African asylum seekers sank off the coast of Yemen. At least six children are among the dead. The refugees had been fleeing violence, poverty and the impacts of climate change in the Horn of Africa. The U.N.'s International Organization for Migration reports nearly 100,000 asylum seekers arrived in Yemen last year, many of them bound for Saudi Arabia and other wealthier nations. That's more than triple the number who made the perilous crossing just two years prior.
