Senior Democrats have claimed they were left in the dark about operation Midnight Hammer, the US's highly coordinated strike on Saturday on Iran's nuclear enrichment program.

Neither Mark Warner, a US senator of Virginia, nor Jim Himes, a representative of Connecticut, both top Democrats on the Senate and House intelligence panels, were briefed before the attack, according to reports.
