Gaza: A Palestinian man was killed and 23 injured in fierce fighting between rival Palestinian security forces in Gaza over unpaid wages.

Smoke from burning tyres blew across Gaza City as forces loyal to President Mahmoud Abbas and the Hamas led-government fired at each other from rooftops near the parliament building.

Tensions rose after Interior Minister Saeed Seyam of the Islamic militant group Hamas ordered his security forces to take to the streets to prevent further violence by striking policemen demanding overdue salaries.

Reports have said a teenage boy was also killed in the fighting.
