Hyderabad, Feb 25 (IANS): Three days after twin bomb blasts killed 16 people and injured over 115 others here, a letter said to be sent by the Lashkar-e-Taiba (LeT) claimed responsibility and threatened more terror attacks.

Bharatiya Janata Party's Andhra Pradesh unit president G. Kishan Reddy received a letter purportedly written by the LeT, threatening to attack Begum Bazaar, a major business centre of the city.

The LeT, in the letter, also claimed responsibility for Thursday's terror attacks in Dilsukhnagar.

Kishan Reddy said the letter written in English and Urdu was handed over to the Abids police station.

Police said they were examining the letter to ascertain its veracity and to trace its origin.

Begum Bazar was one of the areas where the alleged operatives of Indian Mujahideen (IM) conducted reconnaissance to carry out attacks. This was revealed by one of the IM operatives arrested by Delhi Police late last year.

After the terror attacks at Dilsukhnagar, police have already beefed up security at Begum Bazar.
