Iran Press/ Asia: Police in the Balochistan provincial capital of Quetta said a bomb planted on a motorbike detonated as supporters rallied for the Pakistan Tehreek-e-Insaf (PTI) party of jailed ex-prime minister Imran Khan.
"The PTI rally was passing by there but it is not clear whether the rally was a target or not," senior police official Farhan Zahid said.
Waseem Baig, a provincial health department spokesman, said six people were wounded in addition to the four killed.
In a statement, PTI said three of its activists were among the dead at the rally -- a convoy of motorbikes and cars parading through the city to curry support for a candidate ahead of national elections scheduled for February 8.
A party spokesman said it was too soon to say whether they had been deliberately targeted. 219
