Yes it does.
ABC News reports 15 police officers were taken to St. Elizabeth’s Hospital for injuries suffered in the pursuit in which the suspects threw explosives at officers.
18.38 (13.38) Telegraph correspondent Raf Sanchez, who is currently filing from a bagel shop in Montgomery Village, Maryland, is reporting on what is being described as “small arsenal” pipe bombs, grenades and improvised explosive devices that were in the suspects’ possession:
Dzhokhar, the younger brother, hurled some of the bombs at officers as he drove through police lines and broke out of their closing cordon, leaving his older brother dying behind.
Over the police scanner, shocked officers could be heard shouting: “Loud explosion, loud explosion, loud explosion, shots fired, shots fired.”
One police officer was badly wounded in the battle.
Congressman Dutch Ruppersberger, a member of the House intelligence committee, said: “They clearly amassed a small arsenal of explosives.”
Police said this afternoon they were carrying out at least one controlled explosion on Norfolk Street, in Cambridge, not far from where the bombers reportedly share a home.
As well as the two bombs that killed three people at the Marathon, authorities will carefully analyse the latest explosives to figure out how they were built and whether the brothers received help from outside.
The analysis is likely to take place at the government’s specialist lab at Quantico, Virginia.
