Israeli forces in southern Lebanon on Sunday opened fire on protesters demanding their withdrawal in line with a ceasefire agreement, killing at least 15 and injuring more than 80, Lebanese health officials reported.

Israeli forces killed at least three people and injured dozens more in the country’s south, Lebanese officials said. Israel had agreed to withdraw its troops from the area as of Sunday.

The deadline for the Israeli withdrawal from southern Lebanon expired early on Sunday, but troops will remain in some areas as Israel says a ceasefire deal with Hezbollah has not been fully implemented.
