Smoke and missiles have lit up the skies in Israel and Iran in a fierce standoff triggered by fears over Tehran’s expanding nuclear program. Since June 13, hundreds of military strikes have been exchanged as the two nations remain locked in a conflict that shows no signs of abating.

President Donald Trump on Monday kicked off the G7 summit in Canada by saying that he had given Iranian leaders 60 days to cut a deal over their nuclear program before Israel launched its ongoing military assault on the country.

The two powers have been exchanging barrages since Israel attacked Iran and killed many of the country’s top military leaders and scientists.
