Israeli strikes killed some 100 Lebanese Monday in the deadliest and most intense barrage in nearly a year as the Israeli military warned residents in southern and eastern Lebanon to evacuate their homes ahead of a widening air campaign against Hezbollah.

The Israeli military said on Monday it was conducting extensive strikes against targets of the Iranian-backed Hezbollah movement in Lebanon, which come amid some of the heaviest cross-border exchanges of fire in nearly a year of conflict.

More than 100 people have been killed and 400 wounded, “including women, children and paramedics”, from ongoing Israeli airstrikes in south Lebanon today, the country’s health ministry said. This is the single highest daily death toll since fighting between Israel and Hezbollah started in October.
