The Saudi-led Arab military coalition on Saturday admitted responsibility for an air strike the previous day in the Yemeni capital that killed 14 civilians, describing it as a "technical mistake".

The coalition, in a statement carried by the official Saudi Press Agency, said that after a review of the strike investigators found "that a technical mistake was behind the accident".

Witnesses and medics in Sanaa said children were among 14 people killed in Friday's air strike that toppled residential blocks in Sanaa, the latest in a wave of deadly raids blamed on the Saudi-led coalition.
