Gujarat, Mumbai and Delhi are on high alert while warnings of terror threat have been sounded across the country, following intelligence inputs from Pakistan's National Security Adviser (NSA) Nasir Khan Janjua to his Indian counterpart Ajit Doval that 10 terrorists had entered the state to carry out strikes.
This is the first time Pakistan has shared a specific intelligence input with India related to possible terror strikes by Lashkar-E-Taiba and Jaish-e-Muhammed's suicide bombers.
Intelligence agencies believe this infiltration is aimed at creating disturbances on or around Mahashivaratri, which falls on Monday.
Gujarat has been on high alert since Saturday in the wake of the intelligence input. Also, security measures have been heightened at all the sensitive areas, places of worship and public places in the state.
"We had received inputs from centre on Saturday; we've issued a high alert," Gujarat home minister Rajni Patel said.
"Gujarat police is on alert. Gujarat government had asked the centre for NSG teams and the teams have arrived in the state," Patel added.
Important monuments and pilgrimage centres like Somnath Temple, Dwarka Temple, Akashardham, power plants, defence, dams like Sardar Sarovar Dam and security establishments have also been put on alert.
Four NSG teams are also camping in Gujarat are on stand following high level alert.
The warning from Pakistan comes after Border Security Force patrolling team found an abandoned boat off Koteshwar coast in Kutch on Friday.
Altogether five abandoned Pakistani boats were found in the past three months in Kutch.
Earlier, on Saturday, Western Army Commander Lt Gen KJ Singh had disclosed in Pathankot on Saturday that there are some ''disturbing'' inputs about a terror attack in India aimed at creating the ''maximum media impact'' during the Shivratri festival and the ongoing Parliament session. He assured that steps have been taken to deal with it.
