The ongoing Saudi air strikes on Yemen have so far claimed the lives of 13 civilians with more deaths feared, Yemeni sources say.
"Thirteen civilians, including women and children, were killed in the Saudi raids overnight," a civil defense source said on Thursday.
According to witnesses, residents are helping civil defense authorities in the search for any more victims under the rubble of houses damaged in the air raids.
Following the attacks, forces loyal to fugitive Yemeni President Abd Rabbuh Mansur Hadi seized control of the international airport in the southern port city of Aden.
Troops of the 39th Armored Brigade, who are allied to the Houthi Ansarullah movement, had earlier seized the facility.
The Al Arabiya News Channel reported on Thursday that Saudi Arabia has deployed "100 fighter jets, 150,000 soldiers and other navy units" for the military campaign in Yemen.
According to Yemeni sources, parachutists of Saudi-led forces have already landed in Aden.
Yemeni TV has announced that former president Hadi has fled to Oman.
