New Delhi: Pakistan's Interior Ministry chief Rehman Malik on Thursday ruled out India's involvement in attack on Sri Lankan cricket team in Lahore.
Malik said the attack on Sri Lankan cricketers could be the work of al-Qaeda.
Interior Ministry sources also said the police have arrested four key suspects in connection with the attack on the Sri Lankan players on Tuesday in Lahore.
USUAL SUSPECT: Pak's Interior Ministry chief said the attack on Lankans could be the work of al-Qaeda.
"The investigation is going. We are at the moment in an unfortunate situation in Punjab province where this incident took place. There have been large-scale rounding up of people and four of those we believe are involved in the attack. So as far as they are concerned we are catching up with them and that is a good sign," said Pakistani Ambassador to United Nations Abdullah Hussain Haroon.
Almost 300 people, including some Afghanis, have also been detained in connection with the attack in which five security personnel and two other people were killed.
There are reports that the attackers might have wanted to hijack the Sri Lankan team bus, to demand the release of arrested Lashkar-e-Toiba commander Zaki-ur Rehman Lakhvi.
Lakhvi has been detained by Pakistani authorities in connection with the Mumbai terror attacks.
But police say it is too early to say whether the attackers wanted to hold the team hostage.
Initial investigations suggest that they only wanted to attack the team. On Wednesday night Lahore police released sketches of four of the men who attacked the Sri Lankan cricketers.
The police are also scanning hospitals in and around Lahore as they believe that one or more of the terrorists were injured during the shootout.
CCTV footage available show the gunmen were easily able to carry out the attacks, raising serious questions on security.
