By Alexander Cornwell, Parisa Hafezi and Jeff MasonTEL AVIV/DUBAI/WASHINGTON (Reuters) - Israel and Iran kept up their attacks, killing and wounding civilians and raising concern among world leaders at a G7 meeting in Canada this week that the biggest battle between the two old enemies could lead to a broader regional conflict.

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

As the head of the secretive Islamic Revolutionary Guard Corps (IRGC) Major General Hossein Salami, was one of the most powerful men in Iran, overseeing its most potent military arm and reporting directly to its Supreme Leader Ayatollah Ali Khamenei.

Leaders who are not part of the G7 but have been invited to the summit by Carney include the heads of state of India, Ukraine, Brazil, South Africa, South Korea, Australia, Mexico and the UAE. Avoiding tariffs will continue to be top of mind.

The Iran regime is very weak,” Israeli Prime Minister Benjamin Netanyahu said in a television interview. Israeli struck energy facilities and government buildings Sunday.

Amid ongoing strikes between Israel and Iran, Trump is publicly and privately making clear his desire to keep the United States out of the fray for now.

Israel launched an expanded assault on Iran on Sunday, targeting its energy industry and Defense Ministry headquarters, while Tehran unleashed a deadly barrage of missiles.
