Three people have been killed in a drive-by sectarian attack near the north-western Pakistani town of Dera Ismail Khan, police say.
They say that the attack was sectarian and those killed were all were all members of the minority Shia community.
They were shot while travelling on the main highway outside the town.
In a separate incident, police say at least 10 people were injured in a suicide bombing on a security checkpoint in the town of Bannu.
They say that the checkpoint is located next to the local military hospital which the bomber - who was killed in the attack - was trying to target.
Bannu is located next to Pakistan's troubled tribal area of Waziristan.
Police say that the Bannu region is controlled by Taleban and al-Qaeda militants and is used to launch attacks against the Pakistani army and coalition forces in Afghanistan.
"The man was driving a Pajero jeep with explosives which he rammed into the checkpoint," Mohammad Alam Shinwari, a senior Bannu police official, told the BBC.
"The wounded include five security officials," he said.
Bannu's military hospital is located in tightly guarded zone, but security has also been tightened around its military zone.
The BBC's Syed Shoaib Hasan says that the town is located close to the main Taleban stronghold of Waziristan and has been the scene of many suicide bombings. It is also used as a base by militants for attacks into nearby Afghanistan.
