ADEN, Yemen
Saudi-led coalition warplanes on Friday carried out a number of airstrikes on positions held by Yemen's Shiite Houthi group and supporters of ousted President Ali Abdullah Saleh in the southern port city of Aden, according to eyewitnesses.
Warplanes struck the presidential palace in southern Aden's Al-Maashiq district, witnesses said, adding that thick plumes of smoke could be seen billowing from the mountains near the palace.
The extent of the damage caused by the airstrikes, however, could not be immediately ascertained.
On Tuesday, Saudi Arabia announced the end of a month-long air campaign against Yemen's Shiite Houthi militant group.
The following day, however, Riyadh resumed its airstrikes, stressing its right to strike Houthi targets "if necessary."
Yemen has remained in turmoil since a popular uprising in 2011 forced Saleh to step down one year later.
Last September, the Houthis overran capital Sanaa, from which they moved on to extend their control to other parts of the country.
The fall of Sanaa sent shockwaves across the Arabian Gulf, some countries of which believe the Houthis are supported by Shiite Iran.
