QUETTA, Pakistan (AP) - A suicide bomber on a motorcycle targeted a military truck Saturday with a bomb killing eight soldiers and seven civilians in the southwestern city of Quetta, an official and the military said.
He said the nation will celebrate Independence Day with full zeal and fervour to honour the sacrifices of the martyred officers, who laid down their lives for peace and sanctity of the country.
The death toll may climb further as numerous wounded victims suffered serious injuries. The wounded were taken to Civil Hospital and Combined Military Hospital.
According to the secretary for home affairs of the province, Sarfraz Bugti, the firemen were still at work in the night to stop the fire.
Inter Service Public Relations (ISPR) of Pakistan Armed Forces confirmed that eight security personnel were martyred in the blast.
Militants in past have carried out big attacks on Independence Day and other events of national importance.
The group was already known to have collaborated with local activists of pakistan for other attacks.
No terror group claimed responsibility as it has been for previous such incidents in Balochistan, a province rich in oil and gas resources that borders Iran and Afghanistan.
