The city of Boston marks 250 years since the occurrence of the Boston Massacre, known to the British as the Incident on King Street. A confrontation on March 5, 1770 involved British soldiers who shot and killed several residents on a Boston street as tensions between soldiers and colonists rose to a breaking point.

Massachusetts Governor Charlie Baker, distinguished professor Ted Landmark and other officials will speak to mark the occasion at Old South Meeting House. The event begins at 7:05 p.m. and will end close to 8 p.m. with a tolling of bells.

WGBH Forum Network will be there to stream the proceedings live on Facebook and YouTube
