The U.S. government, reacting to Israel's heavy bombardment in Lebanon, said on Sunday that military pressure can enable diplomacy but can also lead to miscalculations. Israeli air attacks battered Beirut's southern suburbs overnight and early on Sunday while dozens were killed separately in Gaza as the Israeli army launched a new incursion in the north.

Israel expanded its bombardment in Lebanon on Saturday, hitting Beirut’s southern suburbs with a dozen airstrikes and striking a Palestinian refugee camp deep in northern Lebanon for the first time.
