HAVANA, Sept 27 (Reuters) - Cuba's electrical grid collapsed late on Tuesday, leaving the entire country without power shortly after the passage of Hurricane Ian, which ravaged the western end of the island with violent winds and flooding.

Lázaro Guerra, Technical Director of the Electric Union of Cuba, said a failure in the national electric system, in part associated with the storm, had affected infrastructure, state-run media reported.

Guerra said the union would work through the night and early Wednesday to restore power.
