Tunisia frees man held over attack on U.S. consulate in Libya

Tunis (Reuters) - Tunisia has freed, for lack of evidence, a Tunisian man who had been suspected of involvement in an Islamist militant attack in Libya last year in which the U.S. ambassador was killed, his lawyer said on Tuesday.

Ali Harzi was one of two Tunisians named in October by the Daily Beast website as having been detained in Turkey over the violence in which Christopher Stevens, the U.S. ambassador to Libya, and three other American officials were killed.
