Pakistan's army says it has started a "comprehensive operation" against foreign and local militants in the northwestern tribal region bordering Afghanistan, a move that effectively ends the government's policy of negotiating with militants.
News of the operation follows last week's militant attack on an airport in Karachi that left nearly 40 people dead, including 10 assailants.
Militants from the central Asian state of Uzbekistan, along with the Pakistani Taliban claimed responsibility for a raid.
The military has not released information on the scope of their new operation, in the tribal region, or what it will entail.
Earlier Sunday, the army said it carried out a series of pre-dawn attacks in North Waziristan in which 80 "terrorists, mostly Uzbek foreigners" were killed.
