At least 28 Indian soldiers have been killed and several others injured after their bus blew up in a landmine explosion in Kashmir. The powerful explosion on the road connecting Srinagar and Jammu in India's Jammu-Kashmir state occurred when a Border Security Force convoy was passing by, said Neeraj Sharma, a spokesman for the paramilitary force. The force is the main component of the Indian military fighting Kashmiri resistance fighters in the region. Sharma said at least 26 soldiers died at the scene of the explosion while 15 others were wounded, many critically. Another police official said the impact of the blast hit a civilian bus that was following the troops. The official said 12 people including three civilians were injured. The explosive had been apparently placed under a small bridge on a highway, added the correspondent. Hizb al-Mujahidiin, the main group fighting Indian rule over the disputed region, has claimed responsibility for the attack. **PHOTO CAPTION*** Indian security man standing on the damaged bus in Kashmir, where Indian soldiers have been killed in a landmine blast.
