KARACHI, Pakistan (AP) — A car packed with explosives went off as a bus carried Chinese engineers to a port project in remote southwestern Pakistan on Monday, killing three of them and injuring eleven other people, police and hospital officials said.
The attack occurred just after 9 a.m. local time while the bus took at least 12 Chinese to the Gawadar port, about 300 miles west of Karachi, near the border with Iran, said Sattar Lasi, the chief of police in Gawadar.
“A car was parked near the port and it exploded as the bus reached the port,” Lasi told The Associated Press.
The motive for the attack was not yet known, said Shoaib Suddle, the police chief in Baluchishtan province, where Gawadar is located. …
The motive for the attack was not immediately clear. Islamic militant groups have targeted foreigners in the past, but never in such a remote part of the country.
Several nationalist groups have also expressed opposition to the project at Gawadar, which aims to develop a deep sea port that will ultimately provide a second option to the heavily trafficked Karachi port terminal.
China is Pakistan’s most important ally and one of its chief trading partners.
The Chinese Embassy was closed Monday, a holiday in Pakistan marking the birth of Islam’s Prophet Muhammad, but a duty officer who identified himself as Cai, said the embassy was monitoring the situation closely. He had no additional information.
