Trapped between dreams of a better life and the harsh reality of war, dozens of African migrants were killed when their detention facility in northern Yemen became the latest victim of US airstrikes.

DUBAI, United Arab Emirates (AP) — Yemen’s Houthi rebels on Monday alleged a U.S. airstrike hit a prison holding African migrants, killing at least 68 people and wounding 47 others. The U.S. military did not acknowledge carrying out the strike.

At least 500 Houthi terrorists, including senior figures behind maritime attacks, have been killed by recent US strikes in Yemen, according to Yemeni officials.
