Firefights and explosions rocks the northern city of Jenin in the occupied West Bank and adjacent refugee camp, a militant stronghold, as Palestinians throw rocks at soldiers and smoke from blasts and burning barricades darkens the sky. Israeli forces killed eight Palestinians in the large-scale operation that the army labelled an "extensive counterterrorism effort" involving air strikes and hundreds of troops. It's the biggest raid in the West Bank for years, featuring armoured vehicles, army bulldozers and drones. IMAGES
