QUETTA, Pakistan (AP) 鈥� A powerful bomb attached to a motorcycle exploded near a vehicle carrying police officers assigned to protect polio workers in on Friday, killing nine people including five nearby children, and wounding 17 other people, officials said.
Local police chief Fateh Mohammad said the attack occurred in Mastung, a district in Balochistan province. He said a motorized rickshaw carrying schoolchildren was nearby when the bombing happened, resulting in the deaths of five children, a police officer and two passersby.
Some of the wounded were moved to a hospital in Quetta, the capital of Balochistan province, said Wasim Baig, a spokesman for the health department. He said seven people died on the spot, while two men who had been critically wounded died at a hospital.
No one immediately claimed responsibility for the attack on police, but suspicion is likely to fall on separatist groups and Pakistani Taliban that have stepped up attacks on security forces and civilians in recent months.
The police chief in Mastung, Rehmat Ullah, said a police van came under attack when it was heading to a health center to escort polio workers for the door-to-door campaign that began on Monday to vaccinate 45 million children under 5, following a surge in new cases.
Pakistan has recorded 41 polio cases across 71 districts so far this year.
The latest attack came days after militants attacked a health center used in the in northwestern district of Orakzai, triggering a shootout that left two policemen dead. Three of the attackers were also killed in the exchange of fire.
Militants in Pakistan often against polio, claiming the vaccination drives are a Western conspiracy to sterilize children. Pakistan and Afghanistan are where the spread of polio has never been stopped.
Prime Minister Shehbaz Sharif and the chief minister of Balochistan, Sarfraz Bugti, both denounced the bombing and vowed to continue the war against insurgents until they are eliminated from the country.
U.N. Secretary-General Antonio Guterres strongly condemned the attack, calling it 鈥渦nacceptable鈥� and urging the government to investigate and ensure those responsible are brought to justice and held accountable, U.N. spokesman Stephane Dujarric said.
Balochistan is the site of a , with an array of separatist groups staging attacks mainly on security forces. The groups, including the Baloch Liberation Army, demand independence from the central government.
The BLA has also attacked foreigners. Last month, it claimed responsibility for a outside an airport in the southern city of Karachi, killing two workers from China and wounding eight people.
Thousands of Chinese workers are in Pakistan as part of Beijing鈥檚 multibillion-dollar , which is building major infrastructure projects.
Beijing has frequently demanded better security for its nationals in Pakistan.
China's ambassador to Pakistan, Jiang Zaidong, urged Pakistan at a seminar this week to take action against the insurgents responsible for 鈥渦nacceptable鈥� attacks on Chinese working on projects related to the China-Pakistan Economic Corridor, a sprawling package that includes road construction, power plants and agriculture.
Pakistan Foreign Ministry spokesperson Mumtaz Zahra Baloch on Thursday expressed her surprise over the ambassador's remarks, saying that Deputy Prime Minister Ishaq Dar, who also attended the seminar, had said 鈥淧akistan is committed to providing full security to Chinese nationals, projects and institutions in Pakistan. Our commitment has been conveyed at the senior most levels of the Chinese government.鈥�
She said Jiang's statement was 鈥減erplexing in view of the positive diplomatic traditions.鈥�
One Pakistani hotel chain, Avari, said the government has instructed that transportation and airport transfers for Chinese guests must be arranged by the host or sponsor 鈥渧ia a bomb/bullet-proof vehicle鈥� with security protocols.
