Indian police shot dead one man and arrested another in the financial hub of Mumbai today during their investigation into last month's train bombings that killed 186 people.
Acting on a tip-off, police surrounded a rundown building in the city centre and began searching for the two suspects linked with the attacks.
The two men were asked to surrender, but instead they opened fired with automatic rifles, forcing police to return fire at around 4.30am local time, police said.
So far, 13 people have been arrested, including an engineer, a journalist, a computer software professional and a doctor, in connection with the July 11th attacks on the city's commuter trains and stations that also wounded about 700 people.
One of those arrested earlier gave police information about the hideout targeted today, Mumbai police's anti-terrorism squad chief said.
An automatic rifle and a box of explosives were found at the site of today's shootout, he added.
Indian security officials say the attacks were carried out by local Muslims who had links to Pakistan. They say the Pakistan-based Islamist militant group Lashkar-e-Taiba is a prime suspect.
