Sana'a, April 22 (IANS): At least 24 civilians were killed on Tuesday when Saudi Arabia-led warplanes destroyed a military camp in Yemen's southern province of Ibb, a media report said.

Warplanes of the Saudi-led coalition forces destroyed a military camp used by the Shia Houthi group as a supply station for their fighters in southern regions, in Ibb, 150 km south of Sana'a, Xinhua reported.

Powerful explosions could be heard in downtown Sana'a on Tuesday afternoon. There were no reports of casualties in Sana'a.

On Monday, at least 60 people were killed and 49 others wounded in Sana'a, in one of the fiercest air raids by Saudi-led coalition forces that began on March 26.

The airstrikes and battles on the ground have killed about 700 people and wounded 3,000, according to reports from the Yemeni health and interior ministries.

Fuel and electricity supply have been cut off for almost a week in Sana'a, Aden and Taiz, the three major cities in the country, where a large number of people do not have access to drinking water.

The exiled Yemeni government said in the Saudi capital of Riyadh that negotiations will not be held until the Houthi fighters are disarmed and retreat from areas they seized since September 2014.

The leader of the Houthi group, Abdul Malik al-Houthi, condemned the Saudi-led military operations and vowed to take tougher actions to confront the coalition forces and Sunni tribal fighters.
