CAIRO, Sept 7 (Reuters) - Egypt's foreign reserves rose to $16.836 billion at the end of August from $16.737 billion at the end of July, the central bank said on Sunday.

Reserves fell sharply after a 2011 uprising that ousted President Hosni Mubarak but rose last year when Gulf Arab states gave billions of dollars of aid after the army deposed elected IslamistPresident Mohamed Mursi.

Reserves stood at about $36 billion before the 2011 revolt. (Reporting by Shadi Bushra; Editing by Alison Williams)
