Israel carried out dozens of strikes on Hezbollah targets in Lebanon on Wednesday, killing a city mayor, toppling buildings and causing widespread destruction in several southern areas.

The latest exchanges in the Israel-Hezbollah conflict came with Israel under increasing international pressure after U.N. peacekeepers in Lebanon were injured, as well as over the escalating humanitarian crisis in the besieged Gaza Strip.

The Israeli military said its warplanes struck dozens of Hezbollah targets in the southern Lebanese city of Nabatieh, where the Iran-backed militant group and its ally Amal hold sway.
