State TV: Explosion kills 1, wounds 3 in southeastern Iran

State TV is reporting that an explosion has killed one person and wounded three others in the restive southeastern Iranian province of Sistan and Baluchistan

The TV report described the explosion that struck a public square in the city of Saravan as a “blind terrorist act” that killed a pedestrian. It wasn't immediately clear who was behind the apparent attack.

After guards at the Iranian border shot and killed several fuel traders last month, unrest gripped the province. Protesters with light arms stormed police stations and government buildings, prompting a government crackdown.

The area is one of the least developed and poorest parts of Iran.
