Security forces mount operation against Karachi killings

"The rangers and police conducted joint operations in various parts of the city overnight," a rangers spokesman told AFP, adding the action continued until morning.

"We interrogated several suspects and formally arrested 14 people."

Security forces targeted Liyari, Orangi and other neighbourhoods troubled by deadly violence blamed on ethnic and criminal gangs that has been plaguing the city for months, leaving hundreds of people dead.

Some of the detained were suspected of involvement in the killings and others indulged in extortion, said the spokesman.

"We have found a large number of weapons and ammunition from them," he added. "The operation against the killers and criminals will continue."

Prime Minister Yousuf Raza Gilani on Monday flew to Karachi and urged the provincial government to restore peace as quickly as possible, underlining how worried authorities are about the situation.

Sindh Information Minister Sharjeel Memon said the government had planned a "surgical operation" to end the killings.

Some 108 people had been killed since last Wednesday, a senior security official told AFP on condition of anonymity because he was not authorised to speak to media.

Security officials said they had found five bodies of people who had been kidnapped in recent days.

The new operation was launched after politicians, industrialists and citizens stepped up calls for the army to intervene to rid the city of the killings.
