President Donald Trump's envoy is set to deliver a firm message to Lebanese leaders during a visit on Thursday: the U.S. will not tolerate the unchecked influence of Hezbollah and its allies over the formation of a new government.

Israel said late Thursday it had struck two sites in Lebanon that allegedly contained weapons of the Hezbollah group, in violation of a ceasefire deal.

A newly appointed U.S. envoy says she hopes Lebanese authorities are committed to making sure that the Hezbollah militant group isn't a part of the new government in any form
