Saudi-led coalition warplanes bombarded a Houthis position near the presidential palace in Aden, eyewitnesses said on Sunday.

Meanwhile, the Operation Decisive Storm warplanes shelled a number of positions affiliated to Houthis and ex-president Ali Abdullah Saleh in Sanaa.

The planes targeted four army camps in Sanaa, eyewitness said.

Operation Decisive Storm entered its 18th day to back the legitimate government of Yemen and deter the Houthi militants from controlling the country.
