Iran's President Mahmoud Ahmadinejad says he suspects Britain may have played a role in twin bomb attacks that killed five people and injured 100 others in southwestern Iran.
Iran's Student News Agency quoted Mr. Ahmadinejad as saying Iranian officials have found what he called British "footprints" in past attacks.
He added the presence of British troops in southern Iraq and near Iran's border is a factor behind insecurity in both countries.
Britain's embassy in Tehran has rejected the allegations and condemned Saturday's attack near a shopping center in Khuzestan province.
In a statement, it said any link between the British government and terrorist attacks in the area is without foundation.
Earlier this month, British officials accused Iran and Lebanese militants of supplying explosives technology to insurgents in Iraq.
