Z is a hypocrite, because in the interview he did for the Miami Herald he spoke about “Israeli mercenaries”. So the Statement was done by him. The other statements were by Romero and due to pressures from the American embassy he apologized.
Note that he didn’t mentioned any Jews now but still mentioned the “gases and electromagnetc rays”.
About were I got the info, I was at the University when I heard a news conference made by Z. TeleSur people were there.
