English.news.cn 2014-07-22 15:06:19 The remains of the 298 victims, mostly Dutch, and the black boxes have become a part of conflict in crisis-plagued Ukraine because they could probably hold evidence telling who and what brought the Boeing 777 down on Thursday as it was flying from Amsterdam to Kuala Lumpur. Under an agreement between Malaysian Prime Minister Najib Razak and Ukrainian insurgents, international forensics experts were finally allowed to access the crash site Monday and collect the bodies. Late on Monday, trucks arrived in Torez, a rebel-held town 15 km from the crash site, with about 200 plastic bags apparently filled with body parts and piles of luggage. British Prime Minister David Cameron said Monday that Europe must keep increasing pressure on Russia, warning that he would push the European Union to consider a new range of "hard-hitting" sanctions against Russia. Vowing to do "everything in its power" to resolve the conflict in Ukraine, Moscow, however, challenged the Western allegations, demanding the United States make public its relevant satellite pictures. Russia also questioned Ukraine over its deployment of Buk anti-aircraft systems not far from the crash site of the Malaysian passenger jet. "For what purpose and against whom were these missile systems deployed? As is known, the (anti-government) militia has no aviation," Andrei Kartopolov, chief of the main operative department of the General Staff, told a news briefing, pointing to a photo of what he said was a Buk system detected 8 km south of Shakhtarsk, where the plane crashed. He added that Russia had not handed Buk systems or other kinds of weapons or military hardware to the pro-independence militants in Ukraine.
