A private jet carrying Libya's military chief and four other people has crashed after takeoff from Turkey's capital, Ankara, killing everyone on board. Turkey said the Libyan military chief was in Ankara for high-level defense talks aimed at boosting military cooperation between the two countries and to address regional issues. Libyan Prime Minister Abdul-Hamid Dbeibah confirmed the death of Gen. Muhammad Ali Ahmad al-Haddad and the others, saying in a statement on Facebook that the "tragic accident" took place as the Libyan delegation was "returning from an official trip to Ankara." He called it a "great loss" for Libya.

On Sept. 11, 2001, nearly 3,000 people were killed as 19 al-Qaida hijackers seized control of four jetliners, sending two of the planes into New York's World Trade Center, one into the Pentagon in Arlington, Virginia, and the fourth into a field in western Pennsylvania. It remains the deadliest terror attack in history.
