The United States does not want to see tensions rise further between Israel and Hezbollah, the US State Department said on Tuesday.
It said Israel has assured Washington it wants a diplomatic solution to the issue.
Hezbollah said it had launched a volley of rockets at an Israeli aerial surveillance base earlier on Tuesday in response to the Israeli military's deepest attack yet into Lebanese territory, with no immediate reports of casualties from the rockets.
The army said it detected a total of 20 launches from Lebanon on Tuesday. It said some were intercepted by air defense systems while others landed in open areas.
