BEIJING (Reuters) -Arab and Muslim ministers called on Monday for an immediate ceasefire in Gaza, as their delegation visited Beijing on the first leg of a tour to push for an end to hostilities and to allow humanitarian aid into the devastated Palestinian enclave. The delegation, which is set to meet officials representing each of the five permanent members of the U.N. Security Council, is also piling pressure on the West to reject Israel's justification of its actions against Palestinians as self-defence. The officials holding meetings with China's top diplomat Wang Yi on Monday are from Saudi Arabia, Jordan, Egypt, Indonesia, Palestine and the Organisation of Islamic Cooperation, among others.
