Security forces in Tajikistan killed two alleged drug smugglers from Afghanistan who crossed the border overnight, the Tajik government said on Friday.

The incursion happened around 1 a.m. in the Farkhor district of the Khatlon region, and border guards and other national security troops disrupted the attempt to smuggle 25 kilograms of hashish, Tajikistan’s State Committee for National Security said.

“The smugglers disobeyed the border patrol’s lawful demands to surrender and offered armed resistance,” the committee said, according to state news agency Khovar. It said two of the smugglers were killed during “the combat operation” and that a third suspect escaped in the darkness.

The committee described the situation at the border with Afghanistan as “under control.”

On April 8, delegates from border agencies of some countries belonging to the Commonwealth of Independent States, a regional group linked by past Soviet ties, assessed the Afghanistan situation during a meeting in Tajikistan.

“There is general agreement that the unstable military-political and economic situation in Afghanistan will have a destructive impact on border security in the Central Asian region in the medium term,” the agencies said.

Last year, a number of Chinese workers in Tajikistan were killed in cross-border attacks from Afghanistan, prompting the Chinese government to urge the Tajik government to take more robust steps to protect Chinese citizens and businesses.

At the time, Tajik President Emomali Rahmon and senior security officials discussed ways to strengthen the southern border with Afghanistan, whose ruling Taliban movement promised to help find the attackers. The border between the two countries is rugged and mountainous in many places and is about 1,370 kilometers long, making it difficult to monitor.
