Security officials and eyewitnesses say airstrikes by the Saudi-led, U.S.-backed coalition fighting in Yemen have killed at least 10 rebels.

They say the Monday air raids hit a military camp in Amran province, also wounding more than 15 others. The officials spoke on condition of anonymity because they were not authorized to brief the media, while the witnesses did so for fear of their safety.

Yemen's conflict pits the government, backed by the coalition, against Shiite rebels allied with a former president. The rebels took over the capital, Sanaa, in September 2014, and the coalition began airstrikes against them in March 2015.

The U.S. military is also helping Yemeni, Emirati and other Arab coalition forces in their fight against al-Qaida in the Arabian Peninsula, the group's affiliate in Yemen.
