On April 28, Saudi air defences intercepted five missiles fired from Yemen following a coalition air strike reportedly targeting Houthi leaders at Interior Ministry in Sanaa.
Yemen's Arabic-language al-Masirah television network, citing its correspondent in the scene, reported on Monday that Saudi fighter jets launched at least two airstrikes against the building, situated in the packed district of Tahrir, killing at least six civilians, including a child, and wounded 86 others, including school children.
The Norwegian Refugee Council also attributed the strikes to the Saudi-led coalition, and said the bombs landed close to the homes of its staff.
A tribal source told Xinhua by phone that Houthis booby trapped and detonated five houses belonging to those linked with army commanders of Saudi backed Yemeni forces in al-Bayda province.
There was no immediate information on casualties, but witnesses said the office, used by the Houthi rebel administration, is normally bustling with employees.
"We were working next door to the presidential offices and heard a plane, and then an explosion", Ahmed Dehashir, a first responder.
Saudi Arabia's Minister of Foreign Affairs Adel Al Jubeir said the Yemeni rebels' actions prove their "terrorist" intentions. "We tried to dig out the dead and wounded from under the debris, and then there was a second strike".
The coalition could not immediately be reached for comment.
The ministry further called on the worldwide community to slam Saudi Arabia's deadly attacks and put pressure on kingdom to halt its war crimes against its impoverished neighbor.
The United Nations has said the Yemeni civil war is the "world's worst humanitarian crisis" - with more than 22 million people, or three-quarters of the population, in need of humanitarian aid and protection.
