Iran has accused the British military of equipping and helping the bombers who killed eight people in southern Iran Tuesday.
Iranian Foreign Minister Manouchehr Mottaki says he has information showing the bombers interacted with British soldiers based in Iraq. Britain denies the charges and any involvement in the twin bombings in Ahvaz.
Last year, at least 12 people were killed in Ahvaz in a series of bombings that Iran blamed on Iranian Arab extremists with ties to foreign governments.
In October, an editorial in Iran's Kayhan International newspaper alleged that British agents were involved in the bombings.
Britain also denied involvement in those attacks. It has accused Tehran of backing insurgents fighting British forces in southeastern Iraq.
Some information for this report was provided by AFP, AP and Reuters.
