ADEN, Yemen: Four newly recruited Yemeni soldiers were killed and dozens others injured in a Houthi drone attack on a pro-government military base in Yemen's southeastern province of Hadramout on Saturday (Sunday in Manila). The targeted military base fully backed by Saudi Arabia was specifically used for training new pro-government Yemeni army recruits. The Houthi rebels based in the capital Sanaa haven't made any comments yet. Yemen has been mired in a civil war since late 2014 when the Houthi militia seized control of several northern provinces and forced the internationally recognized government of President Abd-Rabbu Mansour Hadi out of Sanaa.
