The seven Iranian aid workers who were taken hostage in Libya are to be freed today, Friday, the Libyan Red Crescent Association announced.

Reuters reports that Abdelhamid el-Madani, the head of the Libyan Red Crescent, said: “We are waiting for their release, which can happen any moment now.”

The seven Iranian aid workers arrived in Benghazi on Monday as official guests of the Libyan Red Crescent to assist with relief work in the city. They were kidnapped by an unidentified armed group on Tuesday.

Libyan authorities have not been able to disarm the many groups that armed themselves in the uprising against the Moammar Gaddafi regime last year.

A government spokesman condemned the kidnapping and called on local authorities to bring the perpetrators to justice.

The president of the Libyan Olympic Committee was abducted earlier this month by gunmen in Tripoli, only to be released a week later.
