Gunmen kill three Chinese and driver in Pakistan

KARACHI, Feb 15 (Reuters) - Unidentified gunmen killed three Chinese workers and their driver on Wednesday in a drive-by shooting in southern Pakistan, officials said.

The attack occured near the town of Hub, about 15 km (9 miles) from Karachi and comes just days before President Pervez Musharraf is due to go to Beijing for an official visit.

"They were travelling in a vehicle when armed men sprayed bullets on them," a senior government official told Reuters.

Separatist militants from Pakistan's western province of Baluchistan have targeted Chinese workers in the past, as Chinese firms are heavily involved in infrastructure projects in the province.
