At least four people were killed Tuesday in a bombing targeting an election rally held by a secular party in Pakistan's restive north-western region, officials said, dpa reported.
The bombing targeted a vehicle carrying supporters of President Asif Ali Zardari's Pakistan People's Party in the Lower Dir district of Khyber-Pakhtunkhwa province.
Mehtab Khan, head of the local police station, told dpa that the remote-controlled bomb killed all four people in the vehicle.
