CAIRO - Egyptian and Qatari intelligence officials met in Cairo to discuss a possible reconciliation as part of Saudi efforts to broker an end to the 18-month standoff over Doha's support of the Muslim Brotherhood, security sources said. They said Qatar's intelligence chief, Ahmed Nasser Bin Jassim al-Thani, discussed plans for a meeting between the Egyptian and Qatari heads of state in Riyadh next month. Gulf Arab countries agreed in November to end a long-running dispute with Qatar over its promotion of 'Arab Spring' revolts. Saudi Arabia, which has showered Egypt's government with billions of dollars in aid over the past year-and-a-half, has pushed for a similar rapprochement between Qatar and Egypt.
