Syrian President Bashar al-Assad's feared younger brother Maher has re-emerged in public two years after he was said to have been seriously wounded in a bombing, in a picture on the Internet.

Beirut-based Syrian singer George Wassouf downloaded on his official Facebook page a picture showing Maher wearing a navy blue T-shirt, jeans and looking relaxed.

The picture shows Wassouf standing next to the two brothers on a recent visit to Damascus.
