ROME, Nov 2 (Reuters) - Italy's gas storage facilities are more than 95% full as the country prepares for a winter when supplies might be constrained by the war in Ukraine, gas grid operator Snam said on Wednesday.

"The result achieved is essential for the coming winter and did not appear likely as recently as July when the 90% target itself seemed quite a challenge," said Snam CEO Stefano Venier in a statement. (Writing by Keith Weir, editing by Alvise Armellini)
