British Prime Minister David Cameron said Wednesday that Sunni Islamist insurgents fighting in Iraq were planning to attack Britain and that "ungoverned spaces" where militants thrived had to be shut down.
Cameron spoke out as Iran's president vowed to defend Shiite holy sites in Iraq, where Sunni militants battled their way into the biggest oil refinery in what is rapidly turning into a sectarian war across the frontiers of the Middle East.
Britain has ruled out any military involvement in Iraq, but has sent an "operational liaison and reconnaissance team" to Baghdad and is providing humanitarian aid. It has also pledged to crack down on Britons travelling to the region to fight alongside the insurgents.
