A high alert has been sounded in India's northeast following the Hyderabad terror attack that killed 16 people, an official said Sunday.
"The union home ministry has asked all northeastern states to intensify their vigil," a paramilitary official told IANS.
He said bomb experts and dog squads had been told to scan crowded places.
Four northeastern states - Tripura, Meghalaya, Mizoram and Assam - share a 1,880-km border with Bangladesh. Mizoram, Manipur, Nagaland and Arunachal Pradesh share a 1,640-km border with Myanmar.
Most of the international border is unfenced and runs through dense forests and mountainous, making it porous, vulnerable and advantageous for terrorists and others.
On Feb 21, two powerful bombs, suspected to be planted by terror groups, killed 16 people and injured 117 in Hyderabad.
