Israeli forces fired toward residents of southern Lebanon for a second consecutive day on Monday as people pressed on with attempts to return to their homes along the border, a day after at least two dozen people were killed and scores injured in Israeli attacks, Lebanese officials said.

The Israeli fire on Sunday was the deadliest eruption of violence in Lebanon since the war between Israel and Hezbollah, the Lebanese militia, ended with a truce in November. In the renewed violence on Monday, at least two people were killed and 17 others injured, according to Lebanon’s health ministry.

The Israeli military said in a statement that it had fired “warning shots in order to eliminate threats,” without providing further details about the nature of those threats.

Wire agency photos showed Israeli forces gathered behind makeshift roadblocks, with flattened southern Lebanese villages visible on the rolling hillsides behind them. Some detained men stood crouched alongside a dirt road, blindfolded and with their hands bound as Israeli soldiers stood watch.

The images showed Hezbollah flags on full display and crowds of men and women, in addition to the U.N. peacekeepers and Lebanese soldiers attempting to protect them. Television screens, however, have been flooded with the images of the dead.
