"The force has been put on very high alert along the Indo-Bangladesh border following the armed attack in Dhaka. Security has been tightened," BSF Inspector General (Meghalaya Frontier) P K Dubey said.
Dubey said he had spoken to officials of Meghalaya Police for coordination and sharing of information as soon as news of the killings came in.
Meghalaya has over 100 "gaps" consisting of streams, rivers and drains apart from the unfenced 90-km stretch along the 443 km border with Bangladesh.
Police personnel posted close to the border has been alerted and asked to keep strict vigil in close coordination with the BSF, a senior police officer said.
