AHMEDABAD, India, Wednesday (Reuters) At least 22 people were killed, many of them burned to death, when a bus they were travelling on crashed into a tanker carrying chemicals in the western Indian state of Gujarat on Wednesday, police said.

The luxury bus was on its way from Mumbai, India's financial hub, when it collided head-on with the tanker at Bharuch town, about 200 km (125 miles) south of Ahmedabad, Gujarat's main city.

"Twenty-two people died on the spot while six (injured) have been taken to hospital," Bharuch police chief G.S. Malik told Reuters.
