Massive police operation underway in several Boston neighbourhoods and suburbs
Boston officials have extended to the whole city an order that residents remain inside their homes behind locked doors during the search for one of the two suspects in the Boston Marathon bombings.
Earlier this morning, the other suspect was killed after a shootout with police that followed a robbery and carjacking.
Boston police identified the surviving suspect as Dzhokhar Tsarnaev, 19, of Cambridge, Mass., and said he should be considered armed and dangerous. The second suspect, who died early Friday after a gun battle with police, is reported to be his brother.
