By Alexander Cornwell, Parisa Hafezi and Jeff Mason TEL AVIV/DUBAI/WASHINGTON (Reuters) -Iranian missiles struck Israel's Tel Aviv and the port city of Haifa before dawn on Monday, destroying homes and fuelling concerns among world leaders at this week's G7 meeting that the battle between the two old enemies could lead to a broader regional conflict.

Israel identified and struck missile launchers in Iran overnight, the Israel Defense Forces said Sunday morning. "Over the past hour, the IAF completed an additional series of strikes on storage and missile launch infrastructure sties in western Iran," the IDF said in an update on the Telegram messaging app at about 8 a.m. in Israel.

Dozens of others were injured overnight across Israel, the authorities said. Israel was striking military sites in Iran and the four-day-old conflict showed no sign of slowing.

Iran and Israel have launched a fresh wave of attacks on each other in a development that continues to raise fears of the wider region being plunged into a destabilising conflict. Iranian missiles struck Tel Aviv and the port city of Haifa shortly before dawn on Monday,

Tehran residents tell Newsweek the city is filled with fear and uncertainty, as old memories of past conflicts resurface alongside quiet defiance.

Hundreds of civilians, mostly in Iran, have been killed by dueling airstrikes despite international pleas for de-escalation.

Israel warns "Tehran will burn" if Iran continues firing missiles, while state media say 60 people have been killed in a strike on Iran's capital.
