Libyan authorities have arrested four people in connection with an attack on the U.S. consulate in Benghazi earlier this week that left U.S. Ambassador Chris Stevens and three other Americans dead, Reuters reports.

Authorities have not formally charged the four people arrested.
A no-fly zone has been imposed over Benghazi for the next 48 hours, suspending all flights above the eastern city, AFP reports.
While protests still rage across the Middle East, authorities in Cairo have arrested 37 people in connection with violence outside the U.S. embassy, CNN reports.
