West Bengal government on Wednesday issued a fresh alert in border districts following a series of blasts in Bangladesh.
West Bengal's Inspector-General of Police (Law and Order) Raj Kanojia told PTI that an alert has been in force in the state since Independence day.
A fresh alert was issued following the blasts in Dhaka and other places.
Kanojia said that state police was in constant touch with the Border Security Force for intensifying patrols in areas along the Indo-Bangla border.
A series of near simultaneous explosions rocked various parts of Bangladesh, targeting government offices, courts and press clubs, that left about 100 people injured.
Besides capital Dhaka, at least 49 of Bangladesh's 64 districts were hit by the bombings, suspected to be the handiwork of banned Islamic outfit Jamiat-ul-Mujahideen.
