BREAKING: Twitter is blowing up right now with reports that Bahrain authorities are firing into a crowd of thousands that is assembled for the funeral of those killed in yesterday's crackdown.

This could be a massacre underway.

UPDATE:  This is really happening, folks.  From Twitter user Muiz: "Hospitals not reporting wounds to body or arms, almost all are to the chest & head - live ammo from the ground & air"

From Al Jazeera English's Evan C Hill: "Our correspondent in #Bahrain reports live ammo, not birdshot, not rubber bullets, being used on protesters. #feb17″

From AP reporter Hadeel al-Shalchi:

"Protesters were carrying flowers saying they wanted to deliver it to police. Were shot instead. Blood on street now #bahrain"

"Protesters reached the #lulu square, sat down and army shot into them again #bahrain"
