In photos: Aftermath of Iran's attacks in Israel

Multiple missiles struck northern and central Israel on Sunday, hitting areas including Haifa, Nes Ziona, Rishon Lezion, and Tel Aviv, according to Israeli media reports.

The International Atomic Energy Agency (IAEA) said on Sunday that it had not detected any increase in off-site radiation levels following attacks on three nuclear facilities in Iran, including the Fordow enrichment site.

The agency said it would continue to monitor the situation closely and provide further assessments as more information becomes available.

Iran executed a man accused of spying for Israel’s Mossad intelligence agency, Iranian state media reported on Sunday.

Majid Mosayebi was hanged on Saturday after Iran’s Supreme Court upheld his death sentence, the report said.

The judiciary said Mosayebi had undergone a full legal process before the execution was carried out.

Israel has not commented on the execution.

"I congratulate US President Donald Trump on his historic decision to destroy the 3 nuclear sites in Iran in order to continue the Israeli operation and ensure that Iran does not have a nuclear weapon," Israeli Defense Minister Israel Katz said in a statement.

"The alliance between the United States and Israel is stronger than ever for the benefit of the peace and security of both countries and the entire free world."
