Egypt's prosecutor-general on Wednesday referred four people, including an Austrian citizen and German national, to a state security court on charges of smuggling weapons into the country.
The Austrian and the German, who work for a private security firm, were detained in November along with an Egyptian. Another Egyptian will be tried in absentia, the prosecutor's office said.
The four are accused of "illegally importing unlicensed weapons, ammunition and telescopes into the country and hiding the goods in order to avoid customs duties," it said.
A trial date has yet to be set.
