Both the United States and Russia said on Thursday they could not support a U.N. Security Council resolution calling for a ceasefire in Libya at this time.

Haftar was among officers who helped Gaddafi rise to power in 1969 but fell out with him during Libya’s war with Chad in the 1980s. Haftar was taken prisoner by the Chadians and had to be rescued by the CIA after having worked from Chad to overthrow Gaddafi.

He lived for around 20 years in the U.S. state of Virginia before returning home in 2011 to join other rebels in the uprising that ousted Gaddafi.
