Prime Minister Cameron vowed that Britain will hunt down the Islamic State killers of UK citizen David Haines. He listed steps the UK will take against the Islamic State, including supporting US airstrikes, but did not indicate that the UK will be conducting airstrikes. Police are questioning a man who boarded a crowded train in London during rush hour on Sept. 11 and announced he had a bomb.
