A Palestinian official says Israeli troops have shot and killed a Palestinian during an overnight raid in the West Bank.

Bethlehem Governor Jebren al-Bakri says 19-year-old Jihad al-Jafari was shot in the chest Tuesday morning on the roof of his house in the Deheisha refugee camp as he was watching a disturbance below. Palestinians showed footage of the body being taken to hospital.

The Israeli military says troops on a "routine activity" were attacked with rocks and firebombs in the camp. The military says troops tried to "disperse the turmoil" and, feeling their lives were in danger, opened fire at one of the instigators. It said one Israeli soldier was lightly wounded in the clash.

Israeli troops often carry out overnight raids searching for suspected militants.
