UK's Cameron: Iran embassy attacks "outrageous"

Echoing earlier comments from Foreign Secretary William Hague, Cameron also warned of "serious consequences" for Iran, adding that Britain would consider what measures it would take in the coming days.

"The attack on the British embassy in Tehran today was outrageous and indefensible. The failure of the Iranian government to defend British staff and property was a disgrace," Cameron said in a statement.

"The Iranian government must recognize that there will be serious consequences for failing to protect our staff. We will consider what these measures should be in the coming days."
