Kolkata: In the wake of the deadly terror attack in Dhaka, the Border Security Force (BSF) has intensified vigil across the Indo-Bangladesh border in West Bengal, an officer said on Saturday.

“The vigil across the frontier has been intensified. An alert has been sounded and we are doing the needful,” said a BSF officer.

In coordination with the police, the BSF troopers are also conducting search operations in villages near the Bangladesh border.

Security has also been beefed up in the state’s major installations including the airports and railway stations.

Bangladeshi security forces on Saturday morning rescued some 13 hostages and gunned down six gunmen, ending a long drawn-out siege at a cafe in Dhaka that began on Friday, officials said. Twenty hostages were also killed in the terror attack.

Bangladeshis living in the city as well as eminent personalities in the state have condemned the attack.
