The U.N. human rights office in Geneva said that in the past five days, at least 93 civilians have been killed and 364 wounded in five Yemeni cities engulfed in the violence, including, Sanaa. The overall figures are likely much higher and it was not immediately clear if the casualties cited by Geneva referred to just airstrikes or the strikes and fighting between Yemen's warring factions. The Saudi-led coalition says rebels have set up positions near civilians but that it is doing its best to avoid civilian casualties
