India has said it has become increasingly clear that 'state actors' were involved in executing the 2008 Mumbai terror attacks and that without state support the terror control room could not have been established in Pakistan.

Talking to reporters in New Delhi on Wednesday, Home Minister P Chidambaram said India knew who had trained Ajmal Amir Kasab and nine other terrorists who carried out the terror strikes in Mumbai, who briefed them and how the control room, from where directions were given, had functioned. Mr. Chidambaram said after Kasab's interrogation, evidence clearly pointed to the involvement of state actors and it was corroborated by the statement given by Syed Zabiuddin Ansari, alias Abu Jundal, who was arrested on June 21 after his arrival from Saudi Arabia.
