Israel's Haifa-based Bazan Group said all refinery facilities have been shut down after a power station used to produce steam and electricity were significantly damaged in an attack by Iran, according to a regulatory filing on Monday.

Iranian media hailed the alleged fire, insisting it had been their target for attacks in the North, despite the majority of impacted rockets landing on residential homes.

The barrage of missiles fired between Israel and Iran continued into a fourth day, with Israel saying it hit an Iranian command center, while Iran hit populated areas of Israel, killing at least eight people.
