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.

Emergency services say ten have been killed in Israel, while Iranian state media have given little information about casualties in Iran.

Israel on Sunday issued evacuation warnings to Iranians living near weapons production facilities in Tehran as the two nations continued to exchange missile attacks that began on Friday.

Israeli fighter jets destroyed several aboveground buildings at Natanz, Iran's main uranium enrichment facility, images show.
