Monday saw 14,000 refugees cross the border from Libya into Tunisia and refugees are still streaming into the country. Local officials are overwhelmed by the sheer number of people arriving across the border, where just having enough supplies is a challenge. Meanwhile countries are working to get their citizens out of Libya. Ships have been chartered to take Egyptians to Alexandria; flights are airlifting Bangladeshi workers back to their homeland, and preparations are being made to receive African migrants crossing into Niger. The BBC's Jim Muir reports on the chaos.
