Islamic militants are continuing their assault on the Pakistani government.

Four attacks left at least 37 people dead Thursday.

In the city of Lahore, teams of gunmen targeted three security sites, including a federal agency that fights terrorism and two police training facilities.

Meanwhile in the northwest city of Kohat, a car bomb struck outside a police station, taking down half the building.

President Asif Ali Zardari said the attacks would not deter the government from eliminating violent extremists.

"The enemy has started a guerrilla war," Interior Minister Rehman Malik said. "The whole nation should be united against these handful of terrorists, and God willing we will defeat them."

In the past two weeks, more than 100 people have been killed in a string of suicide attacks in Pakistan.

The Taliban has claimed responsibility for most of them.
