However, on Friday the truce was broken by both sides as forces loyal to President Abd Rabbuh Mansur Hadi launched an offensive and the Houthis fired ballistic missiles on the territory of Saudi Arabia.
"The United Nations lacked powers to stop the war. The truce has not had time to plainly start and has already collapsed. On the same day, when the negotiations began, the Arab coalition’s warplanes launched airstrikes on some areas in Yemen, and still no real truce has begun," Ali Kahum said in a phone conversation.
According to him, the Houthi militants have to defend themselves, and the bombing is still ongoing.
"It seems that the governmental negotiators do not have the right to make decisions, and Saudi Arabia leads the negotiations in the same manner it wages a war against Yemen," Kahum stressed, noting that he had no hope the dialogue to be successful.
Yemen has been engulfed in a military conflict between the government headed by Hadi and Houthi rebels since early 2014.
Since late March, a Saudi-led coalition has been carrying out airstrikes against Houthi positions at Hadi's request.
The United Nations estimated some 5,800 mostly civilians died since Riyadh launched its anti-Houthi campaign. Four out of five Yemenis are believed to be in need of humanitarian aid.
