ROME (AP) — Italian Premier Matteo Renzi says that NATO should use the upcoming summit in Warsaw to consider new security models given the threat of home-grown terrorism.

Renzi told reporters after meeting NATO Secretary-General Jens Stoltenberg on Tuesday that "today the terror threat comes from within, not just from outside."

Renzi said that the threats coming from within require innovative defense solutions and NATO's focus should not only be on the eastern border with Russia.

Turning attention to the Mediterranean rim, Stoltenberg said that the alliance was prepared to help Libya build its own defense institutions, if requested.

NATO is sending a team of experts to assess how the alliance can help the new Libyan government.
