Israel said its troops arrested on Wednesday four Hezbollah operatives, including a local commander, when they entered what it described as a restricted area in southern Lebanon.
The two sides entered into a ceasefire early Wednesday that appears to be holding, but Israel has said it will strike the group in response to any violations.
Prime Minister Benjamin Netanyahu’s office announced the arrests in a statement. There was no immediate comment from Hezbollah.
The statement said Israeli troops have been ordered to prevent people from returning to villages near the border, where the forces are still deployed.
The ceasefire agreement gives Israel and Hezbollah fighters 60 days to withdraw from areas of southern Lebanon near the border. Thousands of Lebanese troops and UN peacekeepers will patrol the area, and an international committee will monitor compliance.
