Home Minister P. Chidamabaram has accused Pakistan of deliberately holding back investigations into the 26/11 Mumbai terror attacks despite concrete evidence against the conspirators being presented to Islamabad linking Lashkar-e-Taiba (LeT) chief Hafiz Saeed to the carnage that killed over 170 people.

"They have not arrested the perpetrators of the Mumbai attack. They are still on Pakistani soil. We have shared the names with them. They are not investigating the case. We have shared complete evidence. The trial has not opened yet. We are thoroughly and totally dissatisfied with the Pakistani response," Chidambaram told Al Jazeera news channel in an interview.
