However, new leads suggested that the militants had entered the Indian waters on early Wednesday morning, the sources said.
This major strike from the banned Lashkar comes six years after it had carried out an audacious attack on Akshardham temple in Ahmedabad in which 25 were killed on September 25, 2002.
Elite National Security Guards had to be airdropped into the complex to rescue 50 people.
The Lashkar-e-Toiba was earlier involved in attacks on RSS headquarters in Nagpur and on Group Regimental Centre of CRPF at Rampur (Uttar Pradesh) in 2007.
