Libyan authorities have arrested four people they suspect of being involved in a Tuesday attack on the US consulate in Benghazi, Libya that killed a US ambassador and three others, the Wall Street Journal reported.
The Journal credited a Libyan official as the source of the news. The Australian reported that Libya's Deputy Interior Minister, Wanis al-Sharef, had confirmed several arrests in connection with the attack that left Ambassador Chris Stevens dead.
According to the Journal, a "multiagency task force" has been convened to investigate the attacks in Libya, where additional suspects are under surveillance, according to the official source.
A spokesman for Libya's Interior Ministry, Abdelmonem al-Horr, told AFP: "All measures are being taken. An independent judicial committee has been set up to carry out an inquiry."
The United States, meanwhile, is also investigating the attacks, which it believes may have been the premeditated work of militants, rather than the spontaneous result of protests-turned-violent, The New York Times reported.
