An international human rights group says Lebanese towns and villages have increasingly imposed curfews on Syrian refugees in the country.

Human Rights Watch says the curfews restrict refugees' movements and "contribute to a climate of discriminatory and retaliatory practices against them."

The New York-based group said in a statement Friday it has identified at least 45 towns and villages across Lebanon that have imposed such curfews.

Lebanon is home to more than 1 million Syrian refugees, who are already seen by many Lebanese as a burden on the tiny country with a population of just 4.5 million people.

Attacks against Syrians, as well as curfews, have intensified since Aug. 2, when Islamic militants crossed into Lebanon and captured more than 20 soldiers and police officers.
