Obama Says Taliban Chief's Death Sends 'Clear Signal'

President Barack Obama said Monday that the violent death of Taliban leader Mullah Mohammed Akhtar Mansour by a U.S. airstrike should send a "clear signal" to anti-American extremists that "we're going to protect our people."

Obama also said Mansour's death was an "important milestone" in the yearslong effort to bring peace to Afghanistan.

"It has been confirmed that he is dead," Obama said Monday during his first visit to Vietnam.
