A suicide bomber rammed a vehicle into a convoy of Chinese engineers in northwest Pakistan, killing six people, police said, the third major attack on Chinese interests in the South Asian country in a week.

"The Chinese embassy and consulates in Pakistan have immediately launched emergency work, demanding that the Pakistani side conduct a thorough investigation into the attack, severely punish the perpetrators, and take practical and effective measures to protect the safety of Chinese citizens," the embassy said in statement.
