A border clash Friday triggered by a smuggling attempt left two Bangladeshi troops dead and one Indian soldier seriously wounded, officials said.

The clash occurred when an Indian border patrol vessel tried to prevent cattle from being smuggled into Bangladesh on a boat, said Ashish Kumar Mitra, the head of India’s Border Security Force.

Bangladeshi soldiers opened fire in Chapainawabganj district, 145 miles west of Dhaka, and Indian troops retaliated, believing they were being targeted by smugglers, Mitra said.

Maj. Syed Abu Hasan of the Bangladesh Rifles border force confirmed that two soldiers were killed, but would not provide details of the cause of the incident, the United News of Bangladesh news agency said.

Hasan and officials in Dhaka could not immediately be reached for comment.

Officers from the two sides were expected to meet later Friday to discuss the incident, Mitra said.

Skirmishes are common along the two South Asian nations’ porous 2,500-mile border.
