Iranian Foreign Minister Abbas Araghchi spoke from Tehran in an exclusive interview with “NBC Nightly News” anchor Tom Llamas.

Iranian Foreign Minister Abbas Araghchi said Thursday that his country is ready for a ground invasion by American troops as the war launched by the United States and Israel has quickly spread across the region. He also refused any negotiations with the U.S. and said that Iran had not asked for a ceasefire.

His comments came after the U.S. and Israeli militaries began a sweeping attack on Iran on Saturday, which decimated its military defenses and killed its top authority, Supreme Leader Ayatollah Ali Khamenei.
