The British embassy in Tehran on 25 March claimed that the stray missile which hit the Abadan refinery in southwest Iran on 21 March was probably an Iraqi rocket. In a statement, the embassy said that the UK Ministry of Defence 'made this conclusion on the basis of the information available and given the disposition of coalition and Iraqi forces in the region at the time,' and has reported its findings to the Iranian government. Washington told Tehran the previous day that investigations were continuing into a number of missiles that accidentally landed on Iranian territory. The official IRNA news agency reported on 22 March that the Iranian government had lodged an official complaint with the UK ambassador to Tehran and with the Swiss embassy, which looks after US interests, over errant missiles and violations of its airspace.
