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

U.S. Deputy Special Envoy for the Middle East Morgan Ortagus said she was "not afraid" of Iran-backed Hezbollah because it was defeated by Israel, stressing the group should not be part of the new Lebanese 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.
