Karachi police chief Ghulam Nabi Memon said the initial investigation suggests it may have been a suicide bomber. He said that closed circuit television footage from the site showed a person dressed in the female burqa head-to-toe covering walking up to the van, followed by an instantaneous explosion.
The three dead Chinese included the director of the Chinese-built Confucius Institute, which offers Chinese language graduate classes, and two teachers.
The fourth fatality was the Pakistani driver of the van, the officials said.
Abdul, Khaliq, a police official, said an investigation was underway.
Woman suicide bomber
The separatist group, Baloch Liberation Army, said a woman suicide bomber was behind the attack.
The “Baloch Liberation Army accepts responsibility of today’s self-sacrificing attack on Chinese in Karachi,” the group’s spokesman Jeeyand Baloch said in a statement published in English to Telegram, adding it was the first BLA mission carried out by a female militant.
The Baluchistan Liberation Army, the militant group in nearby Baluchistan province, has targeted Chinese nationals in attacks in the past.
