Tear gas used to clear Washington, DC protesters

In Washington, D.C. an hour before the 11 p.m.  (0300GMT) curfew on Sunday night, police fired a major barrage of tear gas and stun grenades into the crowd of more than 1,000 people, largely clearing Lafayette Park across the street from the White House and scattering protesters into the street.

Protesters piled up road signs and plastic barriers and lit a raging fire in the middle of H Street.

Some pulled an American flag from a nearby building and threw it into the blaze.

Others added branches pulled from trees.

A cinder block structure, on the north side of the park, that had bathrooms and a maintenance office, was engulfed in flames.
