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.
