cannon

On Monday, police in Kathmandu had fired water cannons, batons and firing rubber bullets to disperse the protesters.

"Tear gas and water cannons were used after the protesters breached into the restricted area," police spokesman Shekhar Khanal told the AFP news agency.

According to him, another tactic is to quickly remove real cannons such as mortars after use and replace them with decoys.

Since the demonstrations began, Indonesian police have used tear gas, water cannons and rubber bullets against protesters, some of whom have lobbed back Molotov cocktails and rocks.

As the cannon fire echoed through Tiananmen Square, even before the first set of troops goose-stepped their way through Beijing's central avenue, the day's most enduring image unfolded.
