A high-level assessment of the security scenario in the light of Indo-Pak tensions was undertaken at a marathon meeting chaired by Prime Minister Manmohan Singh at the Defence Ministry in New Delhi on Saturday night.
Three seniormost ministers, Pranab Mukherjee, A K Antony and P Chidambaram, besides National Security Adviser M K Narayanan, three services chiefs and intelligence chiefs participated in the meeting which lasted around four hours.
There was no media briefing on it.
Meanwhile, the army is understood to have cancelled leave to its personnel till April.
Singh drove from his residence to the South Block housing the defence ministry and held the crucial parleys.
The meeting comes against the backdrop of a new low in ties with Pakistan, which is not not seen as actively cooperating with India in bringing to justice the perpetrators of the Mumbai terror attacks trained from their soil.
Mukherjee had yesterday said that India was obliged to consider the entire range of options that exist in the face of failing to keep its assurances.
Earlier in the day, the Defence Minister presided a separate meeting with Coast Guard and Defence Ministry officials to review the security of Indian coastline where he cleared the acquisition proposals for the sea-guarding agency.
At a previous meeting with the three Services chiefs on December 18, Antony had reviewed the armed force's preparedness to tackle the terror threat facing the country.
