Two US citizens "held" in Yemen have been freed and were taken to Oman on Saturday after mediation by authorities in the Gulf nation, the state-run Oman News Agency reported.

The agency, quoting an Omani foreign ministry spokesman, said the two Americans were brought to Oman aboard an aircraft that earlier Saturday flew to the Yemeni capital to evacuate those wounded in air strikes on a funeral in Sanaa last week. 

It did not identify the US nationals.
