Police reported that while the bomber and his accomplice perished, three persons were hurt in Karachi, a port city.
In Karachi, the port city in southern Pakistan, a suicide bomber set up his explosive-laden vest close to a vehicle with Japanese autoworkers, causing three onlookers to be injured, according to police.
According to local police commander Arshad Awan, the van was headed to an industrial area where the five Japanese nationals work at Pakistan Suzuki Motors.
According to Aswan, the three injured individuals were in stable condition at the hospital and the Japanese nationals fled unscathed on Friday.
Following information about potential attacks on foreign workers in Pakistan on various Chinese-funded and other projects, two security guards were riding in the bulletproof van.
According to police, a motorcycle-riding suicide bomber detonated his vest, and as they were patrolling the area, they shot and killed another attacker.
Senior police officer Tariq Mastoi claimed that the attack was stopped by the cops acting quickly.
The largest metropolis in the nation and the capital of the southern province of Sindh, Karachi, did not immediately receive any claims of responsibility for the attack.
Both Prime Minister Shehbaz Sharif and President Asif Ali Zardari of Pakistan condemned the attack on the Japanese workers.
Chinese people employed in Pakistan on projects associated with the China-Pakistan Economic Corridor (CPEC) have previously been the target of armed organizations. China, one of Pakistan's closest friends, has contributed $62 billion to the CPEC infrastructure project, which consists of a network of roadways connecting the Arabian Sea port of Gwadar with southwest China.
In the northwest region of Khyber Pakhtunkhwa, five Chinese people and their Pakistani driver perished in March when a suicide attacker crashed his car packed with explosives into their convoy close to Besham city. They were traveling around 270 kilometers (167 miles) from Islamabad to Dasu, the location of a hydroelectric project being built by a Chinese corporation.
