Iran and Israel continued on Sunday their aerial attacks, which began Friday with a series of Israeli strikes on Iran.

Smoke and flames filled the sky over Tehran as Israel struck oil and gas facilities in the Iranian capital and targeted more nuclear facilities during attacks that carried on into Sunday after starting two days earlier.

Israel has conducted roughly 150 strikes on Iran over two days, while Iranian forces have fired roughly 200 ballistic missiles at Israeli territory in addition to scores of drones, according to an Israeli military official.

Maj. Gen. Yadlin, who flew in the 1981 Osirak reactor strike, explains why Israel's current operation against Iran represents a complex, multi-week campaign.
