Baghdad ? A Sunni Arab lawmaker is wanted in connection for a string of retaliation attacks and mortar strikes on the fortress-like Green Zone compound after a pair of his senior bodyguards stepped forward with incriminating confessions, a military official said Sunday.

The two ex-bodyguards said Sunni parliament member Mohammed al-Dayni ordered them to carry out a 2007 attack on a Green Zone cafeteria in which a suicide bomber blew up his explosive vest. One lawmaker died and 22 others were wounded.

Police arrested Riyadh Ibrahim Jassim Hussein al-Dayni, al-Dayni’s nephew, and Alaa Khairallah, his assistant, in connection with the case on Feb. 11 and Feb. 17.
