Riyadh Arab Summit to take place April 15: Arab League chief

CAIRO (Reuters) - An Arab Summit in Riyadh where states will seek to prevent Israel from gaining a rotating seat on the U.N. Security Council will take place on April 15, the Arab League chief said in a statement on Tuesday. The summit was postponed from March because the original date clashed with Egypt's upcoming presidential election, the Arab League said last month. Winning a Security Council seat requires a two-thirds majority in the 193-nation General Assembly. Candidates are proposed by the five regional groups but election to the council is voted on by the full assembly. (Reporting by Omar Fahmy; Editing by Hugh Lawson)
