Warplanes from the Saudi-led coalition on Monday hit a military base captured by Yemeni rebels north of Sanaa, killing at least 11, a military official said.

The raid targeted Al-Amaliqa base which was taken over recently by the Houthi rebels in their northern stronghold of Amran province, the official said.

He said 11 people were killed in the first raid to target the base since the rebels seized it.

There was no immediate confirmation of the air strike from other sources.

The government delegation to UN-sponsored peace talks in Kuwait walked out earlier this month in protest at the takeover of the base by the Iran-backed rebels.

The rebels have in their turn complained over alleged air raids by the Saudi-led Arab coalition which they said killed several people.

UN special envoy to Yemen Ismail Ould Cheikh Ahmed on Monday urged Yemen's warring parties to make concessions to save peace talks aimed at ending a devastating 13-month war.
