He added that the conflict in Yemen left more than 80 percent of population in urgent need of aid and called on London to "halt all support for this war and put pressure on all involved to stop the reckless disregard of civilians' safety."
Yemen has been engulfed in a military conflict between the government headed by President Abd Rabbuh Mansur Hadi and Houthi rebels, the country’s main opposition force. The Houthis are backed by army units loyal to former Yemeni President Ali Abdullah Saleh.
Since March 2015, a coalition led by Saudi Arabia has been carrying out airstrikes against Houthi positions at Hadi's request.
