Iraqi Shiite tribesmen parade with their weapons in central Baghdad's Palestine Street as they show their willingness to join Iraqi security forces in the fight against Jihadist militants who have taken over several northern Iraqi cities, on June 17 2014. Faced with a militant offensive sweeping south toward Baghdad, Prime Minister Nuri al-Maliki announced the Iraqi government would arm and equip civilians who volunteer to fight, and thousands have signed up.
