An international advocacy group says Haitian police clashed with hundreds of residents in a camp for people displaced by the 2010 earthquake.

Amnesty International said Tuesday that officers showed up at the makeshift settlement north of Port-au-Prince and fired their weapons in the air while ordering people to vacate.

Residents responded by blocking a highway, and police used tear gas to disperse the crowd, but no one was evicted. Amnesty said two people were treated after being beaten by police.

The apparent effort to evict people from the settlement known as Canaan began in December when Haitian authorities first showed up and told people to leave. It's not clear who owns the land.

Canaan is one of hundreds informal camps that emerged in the aftermath of Haiti's devastating 2010 earthquake.
