A recently retired Israeli spy chief says Prime Minister Benjamin Netanyahu acted irresponsibly regarding Iran's nuclear program and accuses him of prioritizing personal concerns over national interests.

Yuval Diskin, chief of Israel's Shin Bet intelligence agency from 2005 to 2011, has voiced similar criticisms before.

Diskin says Netanyahu tried to convince him and his colleagues to approve what he called an "illegal" decision to attack Iran. He describes attending a "bizarre" meeting with Netanyahu, Defense Minister Ehud Barak and then-foreign minister Avigdor Lieberman, in which they discussed the Iranian nuclear threat over cigars and liquor.

Diskin spoke in an interview to a filmmaker who made a documentary about Israeli spymasters. The interview appeared Friday in Israel's daily Yediot Ahronot.

Netanyahu's office in a text-messaged statement called Diskin's comments "baseless."
