Update: Coalition air strikes kill 136 civilians in Yemen, says UN

Update 2.26pm: The UN human rights office says has verified the killings of 136 Yemeni civilians and other non-combatants in air strikes carried out over 11 days this month by the Saudi-led military coalition batting Yemen's Shiite rebels.

Rupert Colville, of the Office of the High Commissioner for Human Rights, said UN officials are "deeply concerned" about a surge in civilian casualties from air strikes following the killing in early December of Yemen's former president, Ali Abdullah Saleh.
