Several thousand people have protested in Pakistan's Karachi city over the publication in the West of cartoons satirising the Prophet Muhammad.
The protestors joined a rally called by religious parties
In the fourth successive day of demonstrations, tens of thousands of protestors joined a rally called by religious parties.
At least five people have died after protests against cartoons across Pakistan turned violent this week.
Islamic tradition explicitly prohibits any depiction of Allah and the Prophet.
The cartoons, first published by Danish newspaper Jyllands-Posten in September, have angered Muslims worldwide.
The images, that have since been reprinted by several other European publications, include one portraying Muhammad with a bomb in his turban.
Senior police official Mushtaq Shah told the Associated Press that some 10,000 protestors joined the rally in Karachi.
They shouted slogans - 'God's curse be on those who insulted the Prophet' - and burnt effigies of the prime minister of Denmark, reports said.
A leader of the rally said Pakistan should severe ties with European countries where the cartoons were published.
"The government should recall its ambassadors and send back ambassadors of these countries," Muneeb-ur-Rahman was quoted as saying by Reuters news agency.
Security was tight in the restive southern city with armed troops keeping a watch on the streets and from roof tops.

Violence also broke out in the town of Tank in North-West Frontier, near the Iranian border. In Punjab province, hundreds of Islamic students took to the streets of the eastern city of Lahore despite a ban on public protests.
