Water cannons were used to prevent most of the protestersfrom gaining entry to the large security compound situated onthe outskirts of the Belgian capital and close to Brusselsnational airport.
At least one protester was taken to hospital with seriousinjuries after falling on barbed wire, a police spokeswomansaid. "We have arrested over 100 and they are being taken tocourt to be dealt with swiftly."
A NATO official said the compound had not been breached.
"Demonstrations are a feature of democracy. All we hope forwith any such protest is that it is done in a peaceful and safemanner," the official told Reuters.
