A bomb attached to a bicycle exploded outside the office of an election candidate in Khuzdar on Tuesday, wounding nine people including four journalists, police said. The blast happened as Sardar Aslam Bizenjo was addressing a press conference at his office, local police chief Hamid Shakil said. “Someone parked a bicycle outside Bizenjo’s office which exploded during his press conference,” Shakil said, adding that Bizenjo was unhurt and that the injured were shifted to a local hospital. A wave of bomb blasts has gripped the country ahead of the February 18 general elections, claiming the lives of about 100 people so far this year. A suicide car bomber killed around eight people and injured dozen others in an attack on an election candidate’s convoy in North Waziristan on Monday, fuelling fears about the increasingly bloody campaign for the polls. Awami National Party (ANP) candidate Nisar Ali Khan was slightly injured in the blast. On Saturday, a bomb ripped through a similar ANP gathering in Charsadda district.
