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.

President Donald Trump said on Sunday (June 15) that he hopes Israel and Iran can broker a deal but said sometimes countries have to "fight it out" first.

Israel said hundreds of airstrikes over the past two days killed nine senior scientists and experts involved in Iran’s nuclear program, in addition to several top generals.

Aerial attacks between Israel and Iran continued overnight into Monday, marking a fourth day of strikes following Israel's Friday attack. That surprise strike hit the heart of Iran's nuclear program,

to sustain public support he needs to show the military operation is a success and ensure it doesn’t become a protracted conflict, analysts say.

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

Israel warned of more attacks on Iran on Saturday after Tehran fired waves of missiles and drones that killed three people and wounded dozens in Israel.

Israel and Iran aren’t letting up in their attacks.

Iranian state television, long controlled by hard-line supporters of the country’s theocracy, repeatedly aired footage of missile strikes on Tel Aviv throughout the morning.
