Egypt's foreign ministry summoned Qatar's ambassador on Saturday to complain about interference in its internal affairs after Doha criticized Cairo's crackdown on the Islamist Muslim Brotherhood. The formerly close Qatari-Egyptian relationship has soured since the Egyptian army ousted Islamist President Mohamed Mursi, who had been firmly supported by Doha, last July following mass protests against his one-year rule. Cairo then launched a wide crackdown against Mursi's Muslim Brotherhood group and labeled it a terrorist group last week. Qatar said on Saturday that the decision to name the Brotherhood a terrorist organization was "a prelude to a shoot-to-kill policy" against demonstrators who have been staging frequent protests to call for Mursi's reinstatement.
