GLENN VAN ZUTPHEN, WORLD NEWS: Police and protesters have traded gunfire in Belfast in a third night of violence in Northern Ireland. A ban on a Protestant march through a Catholic community in Drumcree on Sunday has tempers flaring. The march is an annual tradition for the Protestant Orange Order. CNN's Nic Robertson has more.</s>NIC ROBERTSON, CNN CORRESPONDENT (voice-over): For the first time in decades, police used water cannons to disperse protesters on the streets of Northern Ireland. The two armored vehicles rented from Belgium were brought in to drive the Protestants back from police lines. The nightly standoff outside Drumcree Church is becoming increasingly violent. This night about 500 demonstrators threw fireworks, rocks and metal bars at police and soldiers. They also set fire to an army truck, positioned to stop them reaching a Catholic neighborhood. In Belfast, dozens of protests blocked roads in Protestant neighborhoods. Police fought running battles with stone-throwing mobs and at one intersection exchanged fire with gunmen shooting from a staunchly Protestant community. Police reported no injuries in that incident. However, they say they do expect casualties in the ongoing violence, much of it aimed at their officers. Northern Ireland's police chief has warned he will not allow his staff to become targets and has urged everyone involved in the escalating troubles to stop.
