Saudi-led air strikes hit the Sanaa headquarters of former Yemeni President Ali Abdullah Saleh's General People's Congress party late on Sunday. Saleh and his followers are allied with the Iranian backed Houthis battling the Arab coalition.
The air raids killed and wounded several people, witnesses and a party official said.
Ismail Ould Cheikh Ahmed, the UN special envoy to Yemen, visited the Yemeni Capital on the same day. Cheikh Ahmed is seeking to arrange a pause in fighting, a “Ramadan Truce” to allow for deliveries of desperately needed humanitarian aid.
The assistant secretary general of the General People's Congress party, Faeqa al-Sayed, said the party headquarters have been destroyed and that that the air strikes were an attempt to cause ongoing UN truce talks to fail. She added that several employees and others were killed in the strikes.
"This will not make us back down on our efforts .... to create the suitable environment to cooperate with the United Nations," she said in a statement on her party's website.
The United Nations has declared the maximum level of humanitarian emergency in Yemen and warned of the imminent collapse of the country’s health system.
Around 20 million Yemenis suffer from a lack of water and a million people have been displaced from their homes as a result of the armed conflict in the country.
A Saudi-led coalition began an extensive air campaign targeting Houthi-held cities across Yemen on March 26 in order to enable President Abd Rabu Mansour Hadi and his government to return to the capital from their self-imposed exile in Saudi Arabia’s capital Riyadh.
Neither the Houthis or President Hadi and his Arab allies are willing to compromise, leading to the stalling of UN sponsored peace talks in Geneva.
