WASHINGTON (AP) — A jury that acquitted a Somali man of piracy charges has been unable to reach a verdict on two hostage-taking charges, resulting in a mistrial Thursday.

The acquittal of Ali Mohamed Ali on the more serious piracy charges remains intact, meaning prosecutors can only attempt to retry him on hostage-taking and conspiracy to commit hostage-taking. A prosecutor said the government hasn’t yet made a decision on that. U.S. District Court Judge Ellen Huvelle scheduled a status conference for next week where the government is expected to reveal its decision. Ali will remain in jail until then.
