The PLA is responsible for defending the city and comprises only mainland troops, with Hong Kong residents unable to serve, but it is barred from interfering in local affairs.
The crash occurred around 1:40 p.m. after a 56-year-old taxi driver lost control of his cab and plowed through a break area where other drivers were standing.
Boston Police, Boston Fire Dept., Boston EMS and the state police were all on the scene.
A police spokesperson was not immediately available to respond to a request for further information.
