Security for visiting Pakistani cricket team was on Saturday strengthened and a country-wide alert sounded by Union Home Ministry against terror strikes in the wake of an e-mail to a television channel threatening an attack on the team and a series of explosions.
An alert was sounded following intelligence inputs suggesting that various sleeper cells of militants outfits like banned Harkat-ul-Jehadi Islamia (HuJI) and Lashker-e- Taiba (LeT) would be targeting some key installations in the country, official sources said.
They said the security for the Pakistani cricket team, now playing a test match here, was further strengthened with more security personnel deployed at the hotels where they are staying.
The states and the Union territories have been asked to keep a strict vigil on their entry and exit points and deploy strengthen intelligence-gathering.
The states have also been asked to ensure beefed-up security to the public transport system which could be the target of militants, the sources said.
