NPR: Four arrested in connection with attack on Libyan consulate

NPR's Dina Temple-Raston says Libyan officials have informed the U.S. that four people are in custody in connection with the attack on the American consulate in Benghazi that killed Ambassador Chris Stevens and three other embassy staffers on Tuesday.

But U.S. officials have yet to interview the detainees, described as "militants" or to verify their involvement in the attack.

Temple-Ralston says it is also unclear whether those arrested are Libyans or foreigners.
