Two gunmen on a motorcycle opened fire on a group of tourists near one of India's biggest mosques today, injuring two Taiwanese and raising concerns about security less than two weeks before an international sporting event in the Indian capital.
The gunmen shot randomly at the tourists as they were about to board a bus parked near the Jama Masjid mosque, police spokesman Rajan Bhagat said.
The 17th century mosque is a popular tourist destination in the heart of the city.
Police launched a massive search for the gunmen and issued a security alert across the Indian capital.
Hours later, the BBC's Hindi language service said it received an e-mail purportedly from the Indian Mujahideen, an Islamic militant group, threatening to attack the upcoming Commonwealth Games.
"We know preparations for the games are at their peak. Beware, we too are preparing in full swing for a great surprise," the e-mail said.
Police cautioned that the e-mail and today's attack could be unrelated.
"We are investigating the attack on the tourists from all angles," said Karnail Singh, a joint commissioner of police.
Officials quickly tried to reassure athletes and the public that security in the city was at an unprecedented high. Thousands of athletes from the Commonwealth of Nations are to compete in the games, which are held every four years.
New Delhi's top elected official, Chief Minister Sheila Dikshit, appealed for calm, declaring the city was safe to host the October 3-14 games in which 71 teams are to take part.
"Please do not panic. An incident like this is something worrying, but nothing to panic about," Dikshit said.
The secretary-general of the games organising committee, Lalit Bhanot, said the shooting would have "no impact" on the event.
Indian authorities "have made elaborate arrangements to provide the Commonwealth Games athletes and officials a safe and secure environment", Bhanot said in a statement.
Federal Home Minister Palaniappan Chidambaram visited the two injured Taiwanese men in the hospital after one was operated on for a stomach wound.
They were in stable condition, said Jaspal Singh, a top police official.
