Social media led authorities to a Benghazi terror suspect

It may be the biggest break in the international manhunt for the Benghazi killers and it's all thanks to social media. This morning, The Daily Beast's Eli Lake reports that Tunisian authorities are holding a man named Ali Ani al-Harzi suspected of participating in the Sept. 11 attacks that killed Ambassador Chris Stevens and three other Americans.

The post from Ali Ani al-Harzi ... was what helped U.S. intelligence locate him and track him down after he fled Libya for Turkey, according to four U.S. officials familiar with the unfolding investigation. 

Apparently, al-Harzi, who is a Tunisian national, was picked up by Turkish authorities shortly after he fled Libya for Turkey and was subsequently sent to Tunisia where he's currently being held in preparation for a court trial. Nobody knows what role he may have played in the attacks or the charges—Lake reports that U.S. and Tunisian officials haven't struck a deal yet on an extradition to the U.S. or any other arrangements for al-Harzi.
