Belgium's Foreign Ministry issued a warning calling on Belgians to avoid trips to Syria and for those there to leave the country "immediately", Le Soir paper reported on Friday evening.
"Trips to Syria are not advised. Belgians still present in Syria are asked with insistence to leave the country immediately," the warning said.
The Belgian embassy in Damascus has been closed since March 30, those who choose to stay can hope for only "extremely limited" consular assistance if needed, it added.
