A Pakistani official on Saturday placed a $100,000 bounty on the head of the maker of an anti-Islam film that has sparked a wave of violence and anger, AFP reported.
Railways Minister Ghulam Ahmed Bilour also called on the Taliban and Al-Qaeda to join the hunt and help accomplish the "noble deed".
Bilour spoke to reporters Saturday in the northwestern city of Peshawar, a day after violent nationwide demonstrations against the "Innocence of Muslims" film left 21 people dead and more than 200 injured.
"I announce today that this blasphemer who has abused the holy prophet, if somebody will kill him, I will give that person a prize of $100,000," Bilour said, urging others to shower the killer with cash and gold.
"I also invite Taliban and Al-Qaeda brothers to be partners in this noble deed," he added. "I also announce that if the government hands this person over to me, my heart says I will finish him with my own hands and then they can hang me."
Protests against the low-budget film, which mocks Islam, have erupted across the Muslim world, leading to more than 50 deaths since the first demonstrations on September 11.
A French satirical magazine's publication this week of cartoons mocking the prophet Mohammed has further stoked anger.
The producer of the film, Nakoula Basseley Nakoula, is reportedly a Los Angeles-based 55-year-old Egyptian Copt and convicted fraudster, currently out on parole.
U.S. media reports say Nakoula wrote and produced the film, using the pseudonym Sam Bacile before being identified. Police questioned him before he went into hiding with his family.
Thousands of Islamist activists in Pakistan staged demonstrations again Saturday but there was no repeat of the previous day's widespread violence.
AFP reported that more than 5,000 protesters, including hundreds of women, marched towards the parliament in Islamabad chanting "We love our Holy Prophet" and "Punishment for those who humiliated our Prophet".
Some 1,500 people from the Islamist Jamaat-ud-Dawa and Sunni religious groups rallied in front of the U.S. consulate in the eastern city of Lahore, chanting "The U.S. deserves only one remedy -- jihad, jihad".
