TEHRAN, Iran: Iranian state television has broadcast purported confessions by more than a dozen suspects in connection with the killing of five nuclear scientists since 2010.

The broadcast showed some of the suspects re-enacting the assassinations in different districts of Tehran.

The TV showed a military garrison it said was a training camp outside Tel Aviv in Israel. It said the suspects took courses there, including how to place magnetic bombs on cars - the method used in the killing of the scientists.

Iran's intelligence chief, Heidar Moslehi, promised recently to provide detailed TV pictures about the case.

Iran has blamed Israel's Mossad as well as the CIA and Britain's MI6 for the assassinations, with support from some of Iran's neighbors. The U.S. and Britain and denied involvement. Israel has not commented.
