Gas canisters fired by police to enforce Baltimore curfew

Police are trying to enforce a curfew on the streets of Baltimore, a night after violence rocked the city.

After an evening of largely peaceful protests, a few hundred people defied the deadline of 10pm local time (0300 BST).

About 2,000 National Guard troops and 1,000 police are on the city streets.
