Lebanon’s state news agency says shells fired from inside Syria have struck Lebanese border villages.

The National News Agency said the shells exploded in four villages late Saturday near the northern border and that residents reported an unpleasant smell after the strikes.

The agency did not report any dead or wounded or say whether government troops or rebels fired the shells.

Shells and gunfire from the Syrian civil war have repeatedly crossed the border into Lebanon, occasionally killing and wounding civilians.

Lebanon and Syria share a complex network of sectarian and political ties that are often enflamed. Many worry that the civil war in Syria between forces loyal to President Bashar Assad and rebels seeking his ouster will spark widespread violence in Lebanon.
