Hezbollah deputy, head of militia that attacked US embassy in Iraq also killed in Soleimani strike

NBC's Tehran Bureau Chief Ali Arouzi notes that the strike that killed top Iran military commander Qassem Soleimani also killed the deputy head of Hezbollah in Lebanon, and the leader of a militia that attacked the U.S. embassy in Iraq. Arouzi says the implications of that could reach into other parts of the Middle East and draw different factions together.
