Death toll from Sunday's overnight U.S. airstrikes on Yemen's capital rises to 12

SANAA, April 28 (Xinhua) -- The death toll from Sunday's overnight U.S. airstrikes on three houses in Yemen's capital Sanaa rose to 12, with 4 others injured, Houthi-controlled health authorities said in a statement late Monday night.

The toll included women and children, the statement said.

The Houthi-run al-Masirah TV reported 15 airstrikes throughout Monday, targeting several locations across northern Yemeni provinces, including the capital Sanaa.

Meanwhile, casualties from U.S. dawn strikes on a migrant center in the northern province of Saada have risen to 68, all of them undocumented African migrants, according to the Houthi television.

The U.S. military was reportedly investigating the incident.

The Houthi group has been controlling much of northern Yemen since a civil war in Yemen broke out in late 2014. Tensions between the Houthis and U.S. forces have escalated sharply since March 15, when Washington resumed airstrikes on Houthi targets in Yemen, a campaign criticized by many regional governments as a threat to wider stability.
