Anger is mixed with worry as Iranians in the capital of Tehran woke up Saturday to images of their country’s retaliatory attacks on Israel.

Israel’s attack on Iran was long in the making – the result of years of meticulous planning by Israel and days of high-stakes talks between Tel Aviv and Washington, officials told CNN.

Israel's attack on Iran raises questions like whether the US will get involved, how Iran will respond, and if a wider conflict may be triggered.

Three people have been killed in Israel, according to officials and local media, with both sides saying the strikes will continue.

President Donald Trump's eventful week included securing a preliminary trade deal with China, deploying National Guard troops to Los Angeles, and responding to Israel's strikes on Iran.

VATICAN CITY (Reuters) -Pope Leo appealed on Saturday for authorities in Iran and Israel to act with "reason" after recent airstrikes and to pursue dialogue. He told an audience in St. Peter's Basilica he was following the situation with "great concern."

Israel's PM says it struck Iran at the heart of its "weaponization programme", but Iran insists its nuclear facilities were peaceful.

The decision comes as officials say they believe that Israel is preparing to launch a military attack on Iran. Tehran condemned the vote.
