Cairo (AFP) - Egypt has added Mohamed Aboutrika - one of the most successful African footballers of his generation - to its terror watch list on suspicions he financed the banned Muslim Brotherhood, his lawyer said on Tuesday.

The Brotherhood was outlawed in 2013, months after the army overthrew Islamist president Mohamed Morsi, who hailed from the movement.

A court official said on Tuesday that Aboutrika was one of more than 1,500 people, including Morsi and other Muslim Brotherhood members behind bars, who were added to the watch list last week.

In 2015 a government committee froze the assets of the former player for Cairo-based club Al Ahly and Egypt's national team, two years after he retired.

According to an anti-terror law imposed in 2015 by President Abdel Fattah al-Sisi, anyone on the country's terror list is subject to a travel ban, with their passport and assets liable to be frozen.

Aboutrika helped deliver repeated victories for Egypt in the African Cup and played on winning Al Ahly teams in the African Champions League.

He publicly endorsed Morsi's presidential bid in 2012. Morsi went on to become Egypt's first democratically elected president, only for the army, prompted by large protests against the Islamist, to oust him one year later and crack down on his supporters.
