Israeli aircraft struck Hezbollah weapons smuggling sites along Syria's border with Lebanon, the Israeli military said Saturday, testing a fragile, days-old ceasefire that has seen continued sporadic fire.

Israeli military jets hit alleged Hezbollah weapons smuggling sites near the border crossing between Lebanon and Syria, according to officials, who allege the Lebanese militant group violated a ceasefire agreement.

The Israeli military said Saturday it had launched a "strike on military infrastructure" at the Syria-Lebanon border. The nation is also warning displaced Lebanese residents from returning south just three days into a ceasefire agreement with the nation.
