LONDON: The ceasefire deal struck this week between Israel and Hezbollah is unlikely to hold, a former head of MI6 has warned. Richard Dearlove, who headed the British intelligence service from 1999 to 2004, told Sky News that the deal, which came into effect on Wednesday, is a “retreaded agreement from 2006.” That initial deal was designed to keep Hezbollah away from the border region with Israel, overseen by the Lebanese military and the UN, but in effect it “did absolutely nothing,” he said.
