Authorities in northwest Pakistan say separate bombings have killed two soldiers and a police officer.
Officials said a roadside bomb targeting a military convoy exploded Tuesday near Bannu, killing the two soldiers and wounding at least four others.
The other attack happened Tuesday near the city of Peshawar, where police say a remote-controlled bomb exploded at a security checkpoint. That blast killed a policeman and wounded at least three others.
No groups have claimed responsibility for the attacks.
Also Tuesday, two major natural gas pipelines were blown up in southwestern Pakistan. There was no immediate claim of responsibility.
Officials said the attack cut off gas service to the Baluchistan region, which could take days to restore.
Some information for this report was provided by AP and Reuters.
