A bomb attack Sunday killed one person and wounded three in southeastern Iran, state news agency IRNA reported, blaming a "terrorist group" linked to Tehran's enemies. 

The attack occurred at about 9:30 a.m. local time (06:00 GMT) in Saravan city, the site of recent violence, in the restive Sistan-Baluchistan province.

A group "linked to global arrogance," a phrase often used in Iran for the United States and its allies, had carried out "the explosion at one of Saravan's squares, leading to one person being killed and the injury of three citizens crossing the street," IRNA said.
