U.S. Secretary of State Hillary Clinton has urged Pakistan to deny safe havens to insurgents and to encourage the Taliban in Afghanistan to enter peace talks after 10 years of fighting.

She spoke Friday in Islamabad during a news conference with Pakistani Foreign Minister Hina Rabbani Khar.

Khar admitted Pakistan could do a better job of cooperating with other countries to clamp down on the militant safe havens along the Afghan border. Khar said there are safe havens on both sides of the Afghan border, but there is “no question of any support” by Pakistani institutions to the militants.

Both U.S. and Afghan officials have accused Islamabad of supporting insurgent groups in Afghanistan. The United States has also been pushing Pakistan to launch a military offensive against militants in the North Waziristan tribal region, the reported base of the al-Qaida-linked Haqqani network.

Clinton was in a second day of meetings with top Pakistani officials in Islamabad. She is traveling with a large U.S. delegation for the talks, including CIA chief David Petraeus and top military officer General Martin Dempsey.

Clinton arrived in Pakistan after meeting in Afghanistan with Afghan President Hamid Karzai.

Meanwhile, officials in northwest Pakistan say at least 30 militants have attacked the house of a prominent anti-Taliban elder's house, killing the elder's two sons and a daughter-in-law. Authorities say the attack happened Friday in Minzare Cheena.
