At least eight Iranian border guards were killed by terrorists in Sistan-Baluchestan province near the border with Pakistan, a provincial official said on Tuesday.
The eight guards were killed in a border area in the southeastern town of Negur on Monday when clashes broke out with terrorists who entered Iran through the Pakistani border, IRNA reported citing Sistan-Baluchestan Deputy Governor Ali Asghar Mirshekari.
Negur is the main town of Dashtiari district in the Chabahar county, one of Iran's southernmost regions.
During the ensuing gun battle, three of the assailants were also killed by Iranian forces.
Sistan-Baluchestan province has seen similar attacks by terrorists who launch hit-and-run attacks and flee to neighbouring Pakistan.
