Dozens of targets hit throughout Sunday, including energy sites, radar systems, missile launchers; refueling plane hit at Mashhad Airport, possibly marking Israel's farthest-ever strike

The Iranian and Israeli strikes mark the most sustained, direct attacks ever between the two rivals. Three people were killed in Israel and at least 78 in Iran, officials said.

Israel and Iran launched fresh attacks on each other late on Saturday, stoking fears of a wider conflict after Israel expanded its surprise campaign against its main rival with a strike on the world's biggest gas field.
