A suicide bomber detonated his explosive-laden vest near a van carrying Japanese autoworkers, who narrowly escaped the attack Friday that wounded three bystanders in Pakistan’s port city of Karachi, police said. The van had been heading to an industrial area where the five Japanese nationals worked at Pakistan Suzuki Motors, local police chief Arshad Awan said. He said police escorting the Japanese returned fire after coming under attack, killing an accomplice of the suicide bomber whose remains were found from the scene of the attack.

“All the Japanese who were the target of the attack are safe,” he said, adding that the three wounded were in stable condition at a hospital.
