Pune: Two students succumbed on Sunday morning to their injuries sustained in the February 13 Pune terror blast, taking the toll to 15, police said.

A 24-year-old student Vikas Suresh Tulsiani died at 11.45am at the Jehangir Hospital here, an official of the Pune police control room said.

Tulsiani, from Delhi, was studying at one of the Symbiosis institutions. Further details of the victim were pending from the hospital authorities, he said.

Earlier this morning, a 23-year-old student from Kolkata, Rajeev Agarwal, succumbed to his injuries.

Agarwal was a final year law student of the Symbiosis Law College and died at 5.45am at the Jehangir Hospital.

Agarwal's father arrived here from Kolkata a few days ago and the body will be handed over after completing the relevant formalities, the official said.

Critical condition

Another five patients continue to be in critical condition in the intensive care units of different city hospitals and 33 more are undergoing treatment.

Among the 15 victims of the terror blast, which ripped through the German Bakery in Koregaon Park area February 13, four were foreigners.

The devastating explosion destroyed the famed eatery, which was located close to the Osho ashram, the leading reason why Pune has become a hub for people from several countries.

A large number of foreigners also study in Pune's educational institutions or work in the city's foreign companies.

The police have struggled to find out who was responsible for the bombing, the worst terror strike in the country since ten Pakistani terrorists sneaked into Mumbai by sea in November 2008 and went on a killing spree.

Investigators believe two men carried the lethal backpack into German Bakery pretending to be customers and left it under a table. When a worker tried to open it after finding it abandoned, it exploded.

No group immediately claimed responsibility. But days later, a little known Pakistan group, Lashkar-e-Taiba Al Alami (LeT-international), called an Indian journalist in Islamabad and owned up to the attack.
