Egypt's Prime Minister Sherif Ismail issued a decree on Sunday revoking the nationality of three Egyptian citizens for joining the military service of foreign country without a permit from the Minister of Defense.

According to the decree, Mohamed Fayez Hussein Hassan Fogo, Ragab Ismail Ragab Bazazou and Walid Salman Hamdan Abdel Rahman El-Talbany were stripped of their Egyptian nationality for joining a foreign army and for working in a foreign security apparatus without a permit from Egypt's defence ministry that is necessary according to constitution.

The prime minister also issued a decree to cancel the Egyptian nationality of Emad Sami Hassenein for becoming an Israeli citizen without a permit from the interior ministry that is likewise required according to the Egyptian constitution.

Article 16 of the current Egyptian constitution gives the prime minister the right to invalidate the Egyptian nationality of any citizen who violates the constitution and the law and become a citizen of another foreign country without receiving permission from Egypt's interior ministry.  

The article also stipulates that the prime minister has the right to annul the nationality of any citizen who joins the military service of any foreign country without receiving permission from Egypt's defence ministry.  

Prime Minister Ismail’s decisions were published in the Egyptian state's official gazette on Sunday.
