A former British diplomat says it is Iran's legal right to protect its sovereignty and the detained Britons should not have entered Iranian waters.
The UK's former ambassador to Uzbekistan, Craig Murray, told the Daily Mirror on Monday, "In international law the Iranian government were not out of order in detaining foreign military personnel in waters to which they have a legitimate claim."
For the Royal Navy to be interdicting shipping within the twelve mile limit of territorial seas, in a region they know full well is subject to a maritime boundary dispute, is unnecessarily provocative, he added.
Murray noted that, "This is especially true as apparently they were not looking for weapons but for smuggled vehicles attempting to evade car duty. What has the evasion of Iranian or Iraqi taxes got to do with the Royal Navy? The ridiculous illogic of the Blair mess gets us further into trouble."
Murray then requested "the Iranian authorities" to "now hand the men back immediately," arguing that "Plainly they were not engaged in piracy or in hostilities against Iran."
He said the Iranians well demonstrated the ability to exercise effective sovereignty over their waters.
