Gunmen on a motorcycle shot dead a local journalist and then fled in a remote part of northwestern Pakistan, police and the victim's family said on Friday.
It was not immediately clear who was behind late on Thursday's attack on Maqbool Hussain Siyal, 32, who worked for a local news agency in the northwestern city of Dera Ismail Khan.
An area police official, Mohammed Jan, said they were still investigating.
"So far we only know that two motorcyclists attacked and killed him, but we have no further details," he said.
The slain journalist belonged to the minority Shiite Muslim community, and his brother Zafar Abbas said he might have been targeted by their "rivals," an implied reference to the Sunni Muslim community.
Pakistan has a history of sectarian violence, mostly blamed on rival Sunni and Shiite extremist groups.
Although Sunni and Shiite Muslims generally live peacefully, extremist elements from both sides often target each other's leader and activists.
The Sunni-Shiite schism, which dates back to the 7th century, stems from a disagreement over who was the true heir to Islam's Prophet Muhammad.
