At least seven people have been killed in bombings in Pakistan, two of which exploded in Islamabad.
The deadliest of the May 24 blasts was in Mohmand tribal region, an area bordering Afghanistan.
Six soldiers were reported killed and three wounded when a roadside bomb exploded.
Spokesman for Tehrik-e-Taliban Pakistan, Umar Khurasani, called RFE/RL's Radio Mashaal to claim responsibility for the attack in the Mohmand region.
Some 20 people in Mohmand have been taken into custody in connection with the attack and a curfew has been imposed in the area.
Earlier, an explosion occurred at 2 a.m. (local time) in an upmarket shopping area close to the city center in Islamabad.
Police officer Chaudhry Hafiz Hussain said one watchman died after being taken to a hospital.
The second blast was described by authorities as a "low intensity" explosion inside a car in a different part of the capital.
There has not yet been any claim of responsibility for the blasts in Islamabad.
The bombings come after three days of air and ground attacks by Pakistan’s army against militant hideouts in the tribal region of North Waziristan near the Afghan border.
The offensive has killed at least 75 people.
Pakistan’s military says those killed were militants, including important commanders.
But locals have told journalists that civilians were among the dead.
