The Israel Defense Forces said late Sunday that troops were carrying out searches along the Lebanese border after forces identified suspicious activity.
Flares were fired into the air and troops dispatched to the scene were carrying out searches, the IDF said.
It did not detail the suspicious sighting nor say exactly where it occurred along the border.
The army said that as a precaution, residents of nearby communities were told to remain in their homes. Several roadblocks were also set up in the area.
