At Least 22 Dead After Saudi-led Airstrikes Hit Army Headquarters in Yemen

At least 22 people were reportedly killed when Saudi-led airstrikes hit the army headquarters in Yemen's Houthi rebel-held capital early Sunday morning.

The airstrikes hit the rebel stronghold in the capital Sanaa, unnamed officials told the Associated Press. Most of those killed were reportedly soldiers, although a few homes were also damaged, according to the AP sources. Video from the scene reportedly showed at least one person trapped in the smoldering rubble calling for help.

According to the Houthi-run SABA news network, at least 44 people were killed, including women and children. Many of the dead were waiting to collect their paychecks at the Yemeni army headquarters, according to SABA and Al Jazeera.

The bombing comes one day after Houthi rebels allegedly fired a Scud missile into Saudi Arabia, a move widely characterized as a major escalation of the conflict. The Saudis suffered no casualties, and fired their own missiles to counter the attack.

Saudi-led airstrikes have been ongoing in Yemen since March 26 in an effort by multiple Middle Eastern states to return former Yemeni president Abd Rabbuh Mansur Hadi to power. The bombing of the Iranian-backed rebels has lead to at least 1,400 casualties in the Yemeni capital, according to the United Nations.

Peace talks between the two sides are scheduled to start on June 14 in Geneva. UN Secretary-General Ban Ki-moon issued a statement urging "all Yemeni parties to engage in these consultations in good faith and without pre-conditions in the interest of all Yemeni people."

Ban also asked for a pause in the ongoing attacks to help secure the safety of civilians on the ground, calling for a "renewed humanitarian pause in order to allow humanitarian assistance to reach all Yemenis in need. This could also help create an atmosphere that is more conducive for peaceful dialogue."
