A former Pakistan senator running in a by-election was killed on Wednesday along with four others in a targeted attack on their car near the border with Afghanistan.
"It appears that a remote-controlled bomb targeted the car carrying the former senator," a district police spokesman told AFP, who asked not to be named because he was not authorised to speak to the media.
"An investigation is currently underway to ascertain the type of explosives used and who was behind it. But miscreants have stepped up their activities in the region lately."
Former senator Hidayatullah Khan, his two companions and two police guards were killed in Bajaur district, just 45 kilometres (28 miles) from the Afghan border, in an area where militancy has been rising since the Taliban took control of Kabul in 2021.
The deadly blast took place ahead of by-elections due on July 11 in which he was running as an independent candidate.
In January, a candidate supporting jailed former prime minister Imran Khan was shot dead in the same district ahead of the general elections, in an attack claimed by the local chapter of the Islamic State group.
Tehreek-e-Taliban Pakistan (TTP) -- a separate group from the Afghan Taliban but with a similar ideology -- and groups linked to it are the most active in the region, largely targeting security officials.
No group has claimed responsibility for Wednesday's attack, which the TTP denied involvement in.
Last month, the government announced the launch of a new counterterrorism operation to support armed forces in their fight against militancy.
