The United States said Friday it was looking into reports that Russia and Iran had signed an agreement for Russia to provide Tor M-1 air defense systems to Iran.
According to the Russian Vedomosti business daily the agreement called for Russia to provide 29 Tor M-1 missiles originally manufactured on orders from Greece. The newspaper cited an unidentified manager at a military-industrial enterprise.
State Department spokesman Sean McCormack said "we are at this point evaluating these reports" and that he could not validate them.

Russia, which has a long and lucrative relationship with Iran, has offered to try to resolve a key dispute by offering to enrich uranium for an Iranian civilian nuclear energy program as a safeguard against Iran using enrichment for weapons purposes.

Burns said sidetracked negotiations between Iran and Britain, France and Germany probably would be resumed in early January, AP reports.
