At least 29 people died in the southwestern province of Beluchistan when a remote-controlled car bomb went off in the town of Hub, as a bus carrying Chinese engineers and workers had just passed.
Authorities said the casualties mainly include police guards, who had been escorting the convoy, and civilians along the road. The Chinese escaped unharmed.
A suicide car bomber killed eight people and injured 30 as he attempted to enter a police academy campus in Hangu, 70 kilometers (50 miles) southwest of the provincial capital Peshawar.
Pakistani authorities link the latest series of terrorist attacks to the recent events in Islamabad, where the army stormed and retook the Red Mosque, seized and held by Islamic radicals for a week.
About 1,000 Taliban-inspired students barricaded themselves in the mosque, a hotbed of Islamic radicalism in Pakistan's capital, July 3, following clashes with government troops. The students had been demanding that Pakistani authorities promote stricter Islamic values in the country.
Officially, 73 Islamic radicals and 10 servicemen died during the army assault, but local media put the death toll far higher. The Frontier Post newspaper cited anonymous sources as saying that over 500 students died, including many women.
A number of extremist organizations have vowed to avenge the Red Mosque attack.
