The United Nations says at least 142 civilians have been killed in Yemen over the past 10 days, sending the total civilian death toll in more than three months of violence above 1,600.

Air strikes and ground fighting have continued despite a U.N.-brokered truce between Shiite rebels known as Houthis and Yemen's internationally backed exiled government and its allies.

Rupert Colville, a spokesman for the U.N. human rights office, said in Geneva that at least 142 civilians were killed between July 3 and Monday and another 224 were injured. That included a total of 76 deaths and 38 injuries in a pair of airstrikes on markets July 6.

Colville said Tuesday that the latest numbers bring the total killed since March 26 to 1,670, while 3,829 civilians have been injured.
