Sudan President Omar al-Bashir 'undergoes surgery

 Sudan President Omar al-Bashir has undergone a minor operation in Saudi Arabia, state media says.

 Mr Bashir, 68, underwent a "successful small" operation in the Saudi capital, Riyadh, they say.

News of the operation comes a day after it was reported that Mr Bashir would receive a medical check-up and meet the Saudi king during his trip.
Last month, officials said he had surgery on his vocal cords in Qatar in August, but was in good health.
On Monday, state news agency Suna, quoting the president's office, said Mr Bashir had gone to Saudi Arabia for "a normal medical review connected with an infection in his throat".
The president is "in good health and is carrying out all his presidential activities normally," it added.
Mr Bashir is wanted by the International Criminal Court for war crimes in the western Darfur region, which he denies.
He has been in power in Sudan since a bloodless coup in 1989.
