French foreign minister Jean-Marc Ayrault says Libyan officials who are blocking the country's unity government will face sanctions.

Ayrault is to meet Friday with the head of Libya's unity government, Fayez Serraj, during a two-day visit to Tunisia. Libya's unity government, based in Tunis, is supposed to replace two rival administrations in Libya, one dominated by Islamists based in the capital Tripoli, the other in the eastern city of Tobruk recognized by the international community.

Ayrault said there is a "shared view" in Europe that sanctions should be imposed on "a few people who are blocking the way for reasons of self-interest and financial interest."

Ayrault will also meet Tunisia's top authorities and attend a commemoration of the Bardo museum attack in which 22 people died last year.
