'NEW METHOD'
Iran's Revolutionary Guards said the latest attack employed a new method that caused Israel's multi-layered defence systems to target each other.
"The initiatives and capabilities used in this operation, despite the comprehensive support of the United States and Western powers and the possession of the most up-to-date and newest defence technology, led to the successful and maximum hitting of the missiles on the targets in the occupied territories," it said.
The Israeli military did not immediately respond to a request for comment on the strikes. Israeli officials have repeatedly said its "Iron Dome" defence system is not 100% and warned of tough days ahead.
The death toll in Iran had reached at least 224, with 90% of the casualties reported to be civilians, an Iranian health ministry spokesperson said.
Israel's military said on Monday morning it had struck again at command centres belonging to the Revolutionary Guard and Iran's military.
