ISLAMABAD (AP) — A rights group says Pakistan’s Supreme Court has halted the execution of a mentally ill prisoner.

In a statement, the Justice Project Pakistan said Monday’s court order halting the execution of Ghulam Abbas, 36, was announced by the Chief Justice Asif Saeed Khosa.

The development came a day after the group said Abbas was being treated with strong anti-psychotic drugs by prison authorities and that the man had a family history of mental illness.

Abbas was sentenced to death in 2006 for fatally stabbing a neighbor in 2004.

He was scheduled to be hung Tuesday at a jail the city of Rawalpindi.

Pakistan is a signatory to international conventions that bar the execution of mentally ill prisoners.
