Airstrikes by the Saudi-led military coalition in Yemen have killed at least 136 civilians and non-combatants since December 6, UN human-rights spokesman Rupert Colville said on Tuesday. Incidents verified by the UN included seven airstrikes that hit a prison in the Shaub district of Sanaa on December 13, Reuters reports. Those strikes killed at least 45 detainees thought to be loyal to President Abd-Rabbu Mansour Hadi, who is supported by Saudi Arabia.
