Indian police said today Pakistan's main intelligence service was connected to last week's suicide attack on the Indian parliament, in a move likely to worsen already tense relations between the nuclear rivals.
New Delhi Police Commissioner Mr Ajai Raj Sharma also told reporters the five attackers, who all died in the raid, were Pakistani citizens and that police had arrested four people and questioned several over the attack in which 13 people died.
"These people have not said this, that Pakistan was in the know of it or that they were directly doing it," he said. "But the things which have come to notice clearly show that ISI was connected with this and if ISI is connected with it then Pakistan must know of it," he said, referring to Pakistan agency Inter-Services Intelligence.
India is pressing Islamabad to act against Kashmiri separatists operating from its soil and blamed for the attack on parliament. New Delhi accuses Islamabad of sponsoring the groups. Pakistan denies this, saying it gives moral, but not military, support to people it calls freedom fighters .
