India says it expects Pakistan to take action in the investigation into last November's terrorist attack in Mumbai.
India's External Affairs Ministry says New Delhi wants Pakistan to help bring the perpetrators of the attack to justice and to dismantle the terrorist infrastructure in Pakistan.
The statement came after India provided more information about Pakistan-based militants suspected of involvement in the Mumbai attacks.
India's Home Minister Palaniappan Chidambaram said a dossier on the suspects given to a Pakistani official answers 30 questions raised by Pakistan about evidence India had presented in January.
India has accused Pakistan-based militant group Lashkar-e-Taiba of training and equipping the 10 terrorists who attacked in Mumbai, India's commercial capital. Pakistan has acknowledged the attacks were partly planned on its soil but wanted more evidence.
Indian officials say the latest dossier contains forensic evidence from the gunmen and information about intercepted telephone conversations between the gunmen and their handlers in Pakistan.
Ten gunmen went on a 60-hour rampage through Mumbai starting November 26, killing about 165 people in raids on two five-star hotels, a train station and a Jewish center. Indian commandos killed nine of the attackers and captured the 10th.
Indian authorities filed charges against the surviving terrorist last month.
Indian leaders have accused Pakistani government agencies of supporting the gunmen, a charge Islamabad denies. Pakistan has detained several Islamic militants, some of whom India has named as plotters of the Mumbai attacks.
