  In Paris, a French foreign ministry spokesman said a steering committee of representatives of nations contributing to the force -- Austria, France, Greece, Italy, Spain and Turkey -- would meet Friday in Rome.
  Pangalos said for his part that the force, due to comprise between 700 and 800 Greek troops, "will not be tasked with disarmament." Instead the Italian-led mission is expected to secure roads, junctions, airports and warehouses and help aid deliveries.
