Two men who spent decades in prison for murdering black activist and civil rights advocate Malcolm X in 1965 have been cleared of wrongdoing in the United States.
The ruling was made by a New York state judge after the Manhattan district attorney said evidence had been withheld in the case and apologised for "violations of law and public trust".
State Supreme Court Justice Ellen Biben vacated the convictions against 83-year-old Muhammad Aziz and Khalil Islam, who died in 2009.
Both were released from prison on parole in the 1980s.
Mr Aziz and two of Mr Islam's sons were present in the court for the decision.
Manhattan District Attorney Cyrus Vance told the court that new exculpatory evidence uncovered during a two-year investigation had made it clear that the two men were wrongfully convicted for murdering Malcolm X.
The evidence included documents that investigators withheld from both defence and prosecution in the case, according to Mr Vance.
"I apologise for what were serious, unacceptable violations of law and the public trust," he said.
Applause broke out in the courtroom as the judge vacated the convictions, after saying she regretted that the court could not give Mr Aziz and Mr Islam back the years they had lost due to the wrongful convictions.
A third man, 80-year-old Mujahid Abdul Halim, confessed to the murder and was released from prison in 2010.
He claimed during their 1966 trial that the other two men were innocent.
All three were members of the Nation of Islam, an African-American Muslim group that espoused black separatism.
Malcolm X rose to prominence as the national spokesman of the Nation of Islam.
He spent more over a decade with the group before becoming disillusioned, publicly breaking with it in 1964 and moderating some of his earlier views on racial separation.
Malcolm X was shot dead by three gunmen on 21 February 1965 as he prepared to deliver a speech in a Manhattan ballroom.
