MOSCOW (AP) — Security officials in Tajikistan say that two people have been killed and one injured after men stormed the border from Afghanistan.

Tajik Border Guards said in a statement on Monday that they are looking for a group of 10 to 12 armed men who crossed the Panj River separating the country from Afghanistan on Sunday. The men, armed with a hand-held grenade launcher and automatic rifles opened fire on three forest rangers, killing two of them and injuring one.

Tajikistan has a long, porous border with Afghanistan, and the area across the Panj is currently under Taliban control.

The incident comes a week before Moscow hosts a Taliban delegation for Afghanistan talks.
