Court officials in Rawalpindi said the hearing had been put off till Saturday. It could not immediately be ascertained whether the judge was unwell or on leave. 

Five prosecution witnesses had been expected to testify at today's hearing. At the last hearing on September 15 too, three officials of the Federal Investigation Agency came to Adiala Jail, where the trial is being conducted, but were unable to testify.

Judge Chaudhry Habib-ur-Rehman of the Rawalpindi-based anti-terrorism court had also admitted an application from Lakhvi's counsel Khwaja Haris Ahmed that said all prosecution witnesses testifying on the same subject should be summoned during the same hearing.

The trial is being conducted behind closed doors at Adiala Jail in Rawalpindi for security reasons.

Pakistani authorities recently increased security at the prison after intelligence agencies reported that the Taliban could attack it to free militants being held there.
