(IRIN) – The heavy fighting came as the UN, along with other relief agencies, Friday launched a humanitarian funding appeal for Yemen, seeking $2.5 billion for 2018 to meet the needs of 10.8 million Yemenis. The document, drafted before the latest events, said violence against civilians was already causing “unspeakable suffering.” Monday saw a dramatic change in the more than two year conflict as former President Ali Abdullah Saleh, who until several days ago had been allied with Houthi rebels, was reportedly killed, according to Houthi media. Unverified images and video circulated on social media of what appeared to be Saleh’s body with a severe head wound.
