Boston bombing suspect Dzhokar Tsarnaev has been charged with federal crimes at the hospital in Cambridge, Mass., where he is being treated, the Associated Press reports. The filing of federal criminal charges against Tsarnaev would appear to end speculation by some officials — including South Carolina Sen. Lindsey Graham — about whether the terrorist attack on the Boston Marathon might make the 19-year-old Chechen immigrant eligible to be treated as an “enemy combatant.”

Dzhokhar’s older brother, Tamerlan Tsarnaev, died after a shootout with police in Watertown, Mass. early Friday morning, following a press conference in Boston where the FBI released photos of the suspected bombers. The younger Tsarnaev was discovered Friday evening, wounded and hiding in a boat parked in the driveway of a house on Franklin Street in Watertown.

UPDATE: NBC News reports:

The hospitalized Boston Marathon bombing suspect, Dzhokhar Tsarnaev, was charged Monday with using a weapon of mass destruction — and the White House said he will be tried in a civilian court.
“He will not be treated as an enemy combatant. We will prosecute this terrorist through our civilian system of justice,” White House Press Secretary Jay Carney said.
“Under U.S. law, United States citizens cannot be tried in military commissions.  And it is important to remember that since 9/11 we have used the federal court system to convict  and incarcerate hundreds of terrorists.”
