The Centre on Wednesday reviewed security at vital installations, including airports, across the country in the wake of the serial blasts in Mumbai last week that claimed 200 lives.
The high level meeting was chaired by Union Home Secretary VK Duggal and attended by Intelligence Bureau Director ESL Naramsimhan, Special Secretary S Rajagopal of the Home Ministry and other officials of the ministry and IB.
During the meeting, Duggal asked all paramilitary forces to maintain a heightened vigil in the wake of intelligence reports that militants were planning to carry out more attacks, official sources said.
Duggal also emphasised the need for a close vigil on sensitive airports as there were reports that militants might target them, they said.
The government has already handed over the responsibility of securing airports to the CISF.
