Islamabad : An explosion in the headquarters of Pakistan's North Waziristan tribal region injured five people Wednesday while another blast in the same area outside an ex-minister's home caused no damage.
Police sources said four civilians and a security person were injured in a roadside blast near a convoy of security forces at Miranshah in the region that borders Afghanistan.
The second blast occurred outside a former minister's home, Dawn News said. No casualty was reported.
The latest attacks followed the death of at least 13 people Tuesday night as a suicide bomber blew himself up outside the venue of a lawyers' rally here to be addressed by Pakistan's suspended chief justice Iftikhar Muhammed Chowdhary.
Some 45 people were injured in that explosion, which was heard over a large area in the Pakistani capital.
Violence has escalated in Pakistan, particularly in the restive North Western Frontier Province (NWFP), following last week's storming of the Lal Masjid in the Pakistani capital to flush out radical Islamists in the mosque.
A suicide bomber exploded himself Tuesday at a checkpoint of security forces in Mir Ali, a major town in North Waziristan, killing three soldiers and two civilians, according media reports.
In another incident, unknown people blew up two security checkpoints in Miranshah early Tuesday, fortunately with no casualties.
Armed tribals in North Waziristan July 15 unilaterally scrapped a 10-month-long peace agreement with the government and threatened to launch guerrilla style attacks against security forces in the region to protest the Lal Masjid attack.
A countrywide security alert has been in place following the deadly attacks July 14-15 in the northwest frontier that left around 70 killed and over 130 injured.
The Pakistan government Monday decided to send more troops to NWFP and tribal areas in the wake of an alarming rise in attacks on security personnel in the region.
