ROME, March 17 (Reuters) - Italy's Pirelli said on Thursday it had halted investments in Russia, excluding those linked to security, and that the activity of its factories in the country would be curtailed.

"Pirelli is against this war... The investments in the local market, excluding those linked to security, have been halted," the tyremaker said in a statement with its annual financial results.

It added that "activities of the factories in Russia will be progressively limited to those needed to guarantee the financing of salaries and social services for employees."

Pirelli manufactures around 10% of its global tyres output in two plants in Russia. (Reporting by Giulia Segreti Editing by Keith Weir)
