UN chief offers condolences over attack in Iran

United Nations Secretary-General Antonio Guterres is offering condolences to Iranians affected by an attack on a military parade that killed 25 people and wounded dozens.

A statement issued Saturday by the U.N. says Guterres also "condemns the attack today in Iran's southwestern city of Ahvaz."

The statement adds that Guterres "expresses his condolences to the families of the victims and to the Government and people of Iran. He wishes those injured a speedy recovery."

An Arab separatist group in Iran says members of the organization carried out the attack.
