A Syrian court has placed a temporary travel ban on prominent businessman Rami Makhlouf, a copy of the court order posted on the Ministry of Justice’s Facebook page showed on Thursday.

Makhlouf, President Bashar al-Assad’s cousin and one of the country’s richest men, has been engaged in a high-profile dispute over funds the government says are owed by his mobile phone company Syriatel.

Makhlouf made a first and rare media appearance earlier this month, contesting recent government measures to seize his assets.
