Islamabad, Dec 19 (IANS): With the Pakistan government deciding to end the moratorium on death sentence in terrorism cases following Tuesday's tragedy in Peshawar, the rules for carrying out the death sentence have been changed in Punjab province in an effort to expedite the execution process.

An inmate on death row could be executed immediately after a black warrant is issued, The News International reported Friday citing jail sources.

According to the previous rules, there was a gap of 14-21 days from when the black warrant was issued and the execution was carried out.

Prime Minister Nawaz Sharif announced Wednesday that the moratorium on the death penalty in terrorism cases had been lifted. The announcement came a day after Tehreek-e-Taliban Pakistan (TTP) militants carried out a brutal attack at the Army Public School in Peshawar killing nearly 150 people, mostly children.

While lifting the moratorium on the death penalty in terrorism cases, the federal government reportedly had asked all the four provincial governments to process the cases of those on death row so that their death warrants or black warrants could be issued on a priority basis.
