Normally, something like this would be frowned upon in diplomatic circles.
US forces have stormed an Iranian consulate in the northern Iraqi town of Irbil and seized six members of staff.
The troops raided the building at about 0300 (0001GMT), taking away computers and papers, according to Kurdish media and senior local officials. ...
The raid comes amid high Iran-US tension. The US accuses Iran of helping to fuel violence in Iraq and seeking nuclear arms. Iran denies both charges.
Tehran counters that US military involvement in the Middle East endangers the whole region.
A local TV station said Kurdish security forces had taken over the building after the Americans had left.
Irbil lies in Iraq's Kurdish-controlled north, about 350km (220 miles) from the capital Baghdad.
Reports say the Iranian consulate there was set up last year under an agreement with the Kurdish regional government to facilitate cross-border visits. ...
Iranian media said the country's embassy in Baghdad had sent a letter of protest about the raid to the Iraqi foreign ministry.
One Iranian news agency with a correspondent in Irbil says five US helicopters were used to land troops on the roof of the Iranian consulate.
