Army Pvt. Chelsea Manning has been assured she will receive gender reassignment surgery while in prison, her lawyer said late Tuesday.

Manning, convicted in the massive leak of national security secrets that propelled WikiLeaks to prominence, is serving a 35-year sentence at the Army's prison at Ft. Leavenworth, Kan. She is eligible for parole in about six years.

Manning ended a hunger strike begun last week after receiving assurances that the government would provide the surgery, said Chase Strangio, her lawyer and an attorney for the American Civil Liberties Union. Manning's doctors recommended in April that she have the male-to-female surgery, Strangio said.

No timeline has been set for her surgery, Strangio said. Manning will meet with her doctors in the next week or two.

Manning sued for access to hormone treatment, and the Army agreed to provide it last year.
