KHARKIV, Ukraine, Ramadan 27, 1435, July 24, 2014, SPA -- A Dutch military aircraft carrying remains of victims from the Malaysian plane disaster departed for the Netherlands Thursday and a second prepared to go, while Australia's government dispatched 50 police officers to London to prepare to join a proposed U.N. team to secure the scattered wreckage, AP reported. All 298 people aboard Malaysia Airlines Flight 17 - most of them Dutch citizens - were killed when the plane was shot down on July 17. Wreckage of the Boeing 777 fell on territory controlled by pro-Russian separatists, and U.S. officials say the plane was probably shot down by a missile, most likely by accident. Australian Prime Minister Tony Abbott, who says he fears some remains will never be recovered unless security is tightened, has proposed a multinational force mounted by countries such as Australia, the Netherlands and Malaysia that lost citizens in the disaster. Foreign Minister Julie Bishop was traveling with her Dutch counterpart Frans Timmermans to Kiev to seek a memorandum of understanding with the Ukraine government to allow international police to secure the area where the wreckage fell, Abbott said. Details including which countries would contribute and whether officers would be armed and protected by international troops were yet to be agreed, Abbott said. --SPA 13:02 LOCAL TIME 10:02 GMT www.spa.gov.sa/w
