CHICAGO - A group of demonstrators are engaging in a confrontation with Chicago police at the end of a NATO protest march, pushing against a line of officers who are trying to keep them from the meeting site.

The police line is several blocks from the lakefront convention centre where President Barack Obama is hosting a gathering of world leaders and there is little chance they will be able to reach the meeting.

Some protesters dressed all in black are trying to move east toward McCormick Place. Some officers are responding by hitting protesters with batons.

The confrontation comes at the end of a march nearly three-hour protest march that was largely peaceful. At the end of the march, several speakers including the Rev. Jesse Jackson asked the protesters to peacefully disperse.
