The US is not planning an imminent attack on Iran in response to the regime's crackdown on protesters, the US ambassador to Israel has told Sky News.

At least 500 people have been killed by Iran's security forces in a week of anti-regime protests. Live updates: https://news.sky.com/story/iran-latest-protests-live-13492391 #iranprotests #
