Authorities in Tehran have blamed Britain for the 24 January attacks that reportedly killed at least eight people and wounded 46 others.
Britain has denied involvement in the attacks. A group campaigning for independence for Iran's Arab minority claimed responsibility for the attacks, which targeted a government building and a bank. The claim of responsibility was posted on a website. It's authenticity could not be verified.
Ahvaz has seen a wave of unrest in the past year, including ethnic riots in April and a series of bombings before a presidential election in June. A double bombing in October killed six people and injured more than 100 others. Oil pipelines in the region have also been sabotaged in recent months.
