Dozens of hardline Iranian students overtook the British Embassy in Tehran on Tuesday, lowering the British flag while chanting, “Death to England” and “The embassy of Britain should be taken over.” They also threw documents out the windows. Reuters reported that the students had taken six embassy workers hostage, citing Mehr, an Iranian news agency, but then said Mehr had removed the report. The incident comes just two days after the Iranian Parliament passed a bill that restricts diplomatic relations with Britain, in light of Britain’s support of the U.S.’s upgraded sanctions on Iran. In a statement, Britain's Foreign Office said: "We are outraged by this. It is utterly unacceptable and we condemn it." Prime Minister David Cameron warned that Iran's "unacceptable failure" to protect the British Embassy would have "serious consequences."
