LONDON, Safar 14, 1437, November 26, 2015, SPA -- Prime Minister David Cameron told lawmakers on Thursday it was time to join air strikes against ISIS militants in Syria, saying Britain cannot "subcontract its security to other countries", according to Reuters. "We do not have the luxury of being able to wait until the Syrian conflict is resolved before tackling ISIL (Islamic State)," Cameron wrote in a response to the committee's objections. He said in his 24-page response the campaign against ISIS was entering a new phase, focusing on command and control, supply lines and financial support - something Britain could contribute well to. "It is wrong for the United Kingdom to sub-contract its security to other countries, and to expect the aircrews of other nations to carry the burdens and the risks of striking ISIS in Syria to stop terrorism here in Britain," he said. --SPA 14:48 LOCAL TIME 11:48 GMT www.spa.gov.sa/w
