CentralSquare.com reports the AIDS Action Committee is opening one of its Boomerangs used-stuff stores at 563 Mass. Ave., to join the existing outlets in Jamaica Plain and West Roxbury.

Somebody on the fourth floor of 7 Yarmouth St. left a candle unwatched long enough this evening for it to start a one-alarm fire that injured two adult residents, two children and a firefighter, the Boston Fire Department reports.

One of the adults had to be hospitalized overnight; the other residents were treated for smoke inhalation and then released, the department says. The firefighter suffered neck burns.

The department estimated damage from the fire, reported around 6:20 p.m., at $200,000.

UPDATE, 3:20 p.m.: BFD reports no more fire, but that there's still smoke from smoldering grease and trash on the tracks under the train as firefighters continue to evacuate 225 passengers. The train itself was not on fire.

An inbound train about 100 feet from Chinatown station appears to be on fire. Passengers are being escorted off the train; Chinatown station is being evacuated.

Daniel Adams reports:

Was waiting on SB Chinatown platform. 3 loud thunks, horrible chemical smoke. Fire near wheels of NB train.
