Pakistani security forces say they have arrested about 40 suspected Taleban fighters.
Pakistani police said they arrested the suspects Tuesday in and around Quetta in southwestern Baluchistan province.
Local police carried out similar raids last month. Security forces arrested more than 50 suspected Taleban fighters, including several receiving treatment for gunshot wounds.
In recent months, the Taleban have stepped up their insurgency against NATO-led troops in southern Afghanistan, with fighters frequently slipping over the border from Pakistan.
Afghan officials say Taleban leaders frequently find shelter in Pakistan.
President Pervez Musharraf recently acknowledged that Islamabad must do more to cut support to Taleban fighters. He has also warned them either to leave or get killed.
