A court in Pakistan's most liberal city has ordered two men to have their noses and ears chopped off as punishment for inflicting similar injuries on a woman they abducted, an official says.

An anti-terrorism court headed by judge Khalid Naveed Dar handed down the ruling in the eastern city of Lahore on Monday, sentencing the two men to life in prison and fining them each 700,000 rupees (about $A9,400).

"The court ordered that the nose and ears of Sher Mohammad and Ammanat Ali be chopped off as part of an Islamic punishment of a nose for a nose and ears for ears," court official Azhar Ameen told AFP on Tuesday.

The men were found guilty of kidnapping a woman who had refused to marry one of them, then hacking off her nose and ears.

Pakistani courts have handed down similar punishments in the past but none were actually enacted and they are frequently revoked on appeal.

Pakistan struggles with religious conservatism. Since July 2007, Islamist militants have waged a campaign of bomb attacks killing more than 2,700 people to avenge the government's alliance in the US-led war on al-Qaeda.
