NEW DELHI, Dec 15: Indian police on Saturday questioned at least four people in connection with the deadly attack on parliament as Islamabad demanded proof that Pakistan-based Muslim groups were behind the assault.

Police said they were holding two Pakistanis and authorities in occupied Kashmir said they had detained two youths for questioning over Thursday’s attack.

In Islamabad, foreign ministry spokesman Aziz Ahmed Khan said that if the Indian government provided evidence to back up its claim that Pakistani-based activists were involved in the attack, “we will examine it.”

But Khan added: “We have neither allowed use of Pakistan soil for terrorism in the past, nor would we allow it in future.”

India’s Home Minister Lal Krishna Advani on Saturday said New Delhi “will wait a few days” to see the reaction from Pakistan and called on Islamabad, as a member of the US-led coalition against terrorism, to take action against the those groups.

Police have conducted several raids around the city since Thursday and are working off clues from calls made on mobile telephones found on the dead gunmen, a senior police official said.—AFP
