At least 26 people have been killed in Pakistan's northwest after the country's air force bombarded tribal areas close to the border with Afghanistan.
Pakistani government officials said the operation carried out on Friday targeted hideouts belonging to pro-Taliban militants, AFP reported.
Pakistani fighter jets killed at least 18 people in the tribal district of Orakzai, said local government official Zaman Khattak.
He added that the airstrikes took place in the Mehmood Zai area, a known militant bastion in Orakzai.
Eight others were killed in a separate air raid in neighboring Kurram, according another local official.
The attacks come as the United States has been mounting pressure on Islamabad to step up its military operations against Taliban and al-Qaeda-linked militants in the tribal belt on the Afghan border.
On Friday, US Secretary of State Hillary Clinton said she was even more committed to Pakistan after al-Qaeda leader Osama bin Laden's killing, insisting that Islamabad needed to do more in its battle with militants.
Earlier in May, US President Barack Obama claimed US forces had killed the al-Qaeda leader in his hideout in the Pakistani city of Abbottabad.
Washington rushed into a sea burial for bin Laden and did not agree to release any pictures of his dead body or to perform a DNA test to confirm his identity.
Pakistan has since been rocked by a new wave of terror attacks, with the country's main militant faction vowing to strike Pakistani and American targets to avenge bin Laden's death.
On the eve of Clinton's visit, 35 people were killed in a car bombing attack outside a Pakistani police station in the northwestern town of Hangu late Thursday. Press TV
