Two suspected militants have been killed in a gunbattle with police in the Indian capital, Delhi, police have said.
The explosives were found in a routine check, police said
The men were alleged to be members of the Jaish-e-Mohammad militant group, one of two Kashmiri separatist organisations which India has accused of carrying out a deadly attack on its parliament two years ago.
The shooting came hours after police found an bag containing more than 20 kilograms of explosives at Delhi's main railway station.
India has been on high alert since Monday, when 52 people died in two simultaneous car bombs in the country's commercial capital, Bombay, also known as Mumbai.
Earlier on Saturday, officials in Indian-administered Kashmir said one of the leaders of Jaish-e-Mohammad had been killed in a gun battle with security forces.
India accuses the militant, Ghazi Baba, of being one of the organisers of the 2001 attack on parliament.
His death has not been independently verified.
The Delhi gunbattle took place near a park in the eastern part of
the city, officer Sunni Lal said at the local police station.
"There two were terrorists and they were killed. We have no further details," the officer said.
It was not clear whether the shootings were linked to the explosives, which were found during a routine check.
"It was an unclaimed bag and contained about 150 gelatin sticks weighing about 21kg (46 lb)," a police spokesman said.
After finding the bag, police sealed off the area and bomb disposal experts were called in to defuse the explosives.
"These were dangerous explosives and had the potential to cause extensive damage," India's top police official Neeraj Kumar told the Star Television channel.
The capital's railway station is one of India's busiest, handling thousands of passengers every day.
India has blamed the Bombay bombings on the Lashkar-e-Toiba, the other Kashmiri militant group it accuses of carrying out the parliament attack.
The organisation is based in the Pakistani-controlled part of the disputed state of Kashmir.
Delhi has demanded that Islamabad hand over 19 suspects wanted in connection with other attacks, but Pakistan has denied giving shelter to any such suspects.
On Friday, India ruled out any direct talks with Pakistan until violence ends in the disputed state of Kashmir.
Pakistan has rejected India's accusations.
