Lawyers for a Ukrainian military officer imprisoned in Russia say she's ready to end her nearly three-month hunger strike if she's offered a balanced diet.

Nadezhda Savchenko has been in Russian custody since June on charges that she aided a mortar attack that killed two Russian journalists covering the war between Ukrainian troops and Russia-backed separatists. She began a hunger strike on Dec. 13 and concerns for her health have risen sharply in the past week.

The Russian prison service claimed on Thursday that she agreed to consume chicken broth.

But her lawyers on Friday posted photos on Twitter of a handwritten statement from Savchenko saying the high-fat broth was dangerous to her health and asking for pureed fruits and vegetables.

Prison service officials could not be reached for comment.
