Egypt's Prime Minister Hazem Beblawi has said Islamist militants in the Sinai peninsula are becoming a threat to foreign tourists.
Officials in Egypt said they were taking seriously a reported ultimatum by Islamist militant group Ansar Beit al-Maqdis for tourists to leave the country.
According to the BBC, the threat was reportedly made on a private Twitter account affiliated with the group, giving all tourists time until Thursday to leave Egypt or face attacks.
