Saudi-led coalition warplanes on Wednesday bombed rebel military camps in Yemen's capital Sanaa, killing at least 40 people and injuring 100 others.

A local official in Sanaa told rebel-controlled Saba news agency that Saudi bombardments targeted Nahdain Mountain, a Special Security Forces camp, health and commercial facilities and residential areas. He further said the airstrikes have not ended and so far have targeted a number of areas in the capital.

"We felt the hospital was shaking, people were panicking, the explosion was huge and those injured are still being admitted to the hospital," a nurse in Al Sabeen Hospital located close to military camp told Yemen Times.

The Saudi-led group began airstrikes on March 26 against Iran-backed Shiite Houthi rebels in a bid to restore former President Abedrabbo Mansour Hadi to power, according to the AFP.

In the northwestern province of Hajja, the airstrikes killed at least 39 people, most of them civilians. Warplanes also targeted a naval base in Hodaida city on Wednesday, Al Arabiya News channel reported.

United Nations-facilitated peace talks for Yrgetemen - which were due to be held in Geneva on May 28 - have been postponed after Houthi rebels refused to meet demands for withdrawal. UN Secretary-General Ban Ki-moon has asked his special envoy to Yemen, Ismail Ould Cheikh Ahmed, to postpone the talks, UN spokesman Stephane Dujarric said in a statement.

"The Secretary-General is disappointed that it has not been possible to commence such an important initiative at the soonest possible date and reiterates his call for all parties to engage in United Nations-facilitated consultations in good faith and without pre-conditions," Dujarric added in a UN statement.

At least 1037 civilians, including 130 women and 234 children, have lost their lives in Yemen between March 26 and May 20, the office of the UN High Commission for Human Rights (OHCHR) estimated.
