Foreign intelligence agencies have warned India that terror group Lashkar-e-Taiba may be planning an attack in the country to coincide with US President Barack Obama's visit next month.

Special attention is being paid to the five terror suspects who escaped from a prison in Madhya Pradesh in October last year and have still not been found, say sources in Indian intelligence agencies.

The Lashkar is a terror outfit based in Pakistan, which was responsible for the 26/11 Mumbai attacks in 2008.

Recent phone intercepts reveal Lashkar handlers talking to escaped terror suspects, said intelligence sources, reports NDTV.

Obama will be the chief guest for next month's Republic Day celebrations. Obama, who also visited India in 2010, will have the distinction of being the first US president to visit India twice while still in office.

The Home Ministry is also keeping an eye on imprisoned members of the banned Students Islamic Movement of India (SIMI), who might be planning a "lone wolf" attack.

On Wednesday morning, Delhi police officials reviewed security arrangements at schools after yesterday's deadly strike in Peshawar in North West Pakistan killed 132 students in an army-run school.
