British Prime Minister David Cameron will interrupt his holiday and return to London on Wednesday after Islamic State released a video that appeared to show the beheading of a man identified as a U.S. "He will meet with the Foreign Secretary and senior officials from the Home Office, Foreign Office and the agencies to discuss the situation in Iraq and Syria and the threat posed by ISIL terrorists," a statement from Cameron's office read. Britain said earlier it would also be working closely with the United States to identify the man shown in the video holding a knife, who appeared to have a British accent.
Israeli warplanes struck Gaza, killing the wife and child of Hamas's top military chief, the Islamist movement said Wednesday after truce talks in Cairo collapsed in a storm of violence. It was not immediately clear whether Mohammed Deif himself, who has topped Israel's most wanted list for decades, was killed or wounded in the strike which hit a house in Gaza City late on Tuesday. Hamas vowed bloody revenge, saying Israel had "opened the gates of hell". The deadly attack came just hours after a resumption of the fighting in and around Gaza after more than a week of calm as Egyptian negotiators pushed the warring sides to broker a decisive end to six weeks of bloodshed.
