British Prime Minister Keir Starmer confirmed the United Kingdom is building up its forces in the Middle East in response to Israel and Iran’s war — as he and other European politicians continued to implore both sides to de-escalate.

The Israeli army says 200 jets struck more than 100 sites across Iran in a large-scale attack. Israel’s military says it launched a wave of strikes on Iran, hitting key nuclear facilities and killing senior Iranian commanders and nuclear scientists in a major attack.

WASHINGTON (AP) — President Donald Trump says an Israeli attack on Iran over Tehran’s nuclear program is not imminent but “could very well happen.” “I don’t want to say imminent, but it looks like it’s something that could very well happen,” Trump told reporters at the White House on Thursday.

"We have taken note with great concern of the various statements concerning a considerable increase in enrichment capacity, and in particular, the establishment of new infrastructure."

The reaction was noticeably different on Friday than it was after the last time Israel attacked Iran, when several countries provided backup and resources.

Iran has warned the UK, US and France their bases in the region will be targeted if they help Israel stop Tehran's strikes. Follow the latest updates below.
