Yemen missile, drone attack kills at least 70 soldiers

At least 70 Yemeni soldiers have been killed in missile and drone attacks blamed on Huthi rebels, on a mosque in the central province of Marib, medical and military sources said Sunday.

Saturday's strike follows months of relative calm in the war between the Iran-backed Huthis and Yemen's internationally recognised government which is backed by a Saudi-led military coalition.

The Huthis attacked a mosque in a military camp in Marib -- about 170 kilometres (105 miles) east of the capital Sanaa -- during evening prayers, military sources told AFP.

A medical source at a Marib city hospital, where the casualties were transported, said that at least 70 soldiers were killed and more than 50 injured in the strike.

The attack came a day after coalition-backed government forces launched a large-scale operation against the Huthis in the Naham region, north of Sanaa. Fighting in Naham was ongoing on Sunday, a military source said according to the official Saba news agency.

"Dozens from the (Huthi) militia were killed and injured," the source added. Yemeni President Abedrabbo Mansour Hadi condemned the "cowardly and terrorist" attack on the mosque, Saba reported.

"The disgraceful actions of the Huthi militia without a doubt confirm its unwillingness to (achieve) peace, because it knows nothing but death and destruction and is a cheap Iranian tool in the region," it quoted Hadi as saying.

The Huthis did not make any immediate claim of responsibility and the Saba report did not give a death toll.

The uptick in violence comes shortly after United Nations envoy Martin Griffiths welcomed a sharp reduction in air strikes and the movement of ground forces.

"We are surely, and I hope this is true and I hope it will remain so, witnessing one of the quietest periods of this conflict," he said in a briefing to the UN Security Council on Thursday.

"Experience however tells us that military de-escalation cannot be sustained without political progress between the parties, and this has become the next challenge."
