Egyptian Prime Minister Hazem Beblawi has said Islamist militants in the Sinai peninsula are becoming a threat to foreign tourists, state TV reports.
Officials say they are taking seriously a reported ultimatum by Islamist militant group Ansar Beit al-Maqdis for tourists to leave the country.
The threat was reportedly made on a private Twitter account affiliated with the group, according to Reuters.
The Egyptian government has struggled against rising militancy in the Sinai.
