The suspects have been arrested for involving in Sunday's car bombings in an eastern Libyan town where Prime Minister Abdullah Al-Thinni was meeting a UN Special Envoy, Libyan Interior Minister Omar Al-Sanki said on Monday.
Al-Sanki said that the bombings aimed at destabilizing the security and challenging the government's ability to restore stability, but he did not say how many suspects have been arrested.
Two car bombs exploded on Sunday near the security directorate of the eastern archaeological town Shahat, where the interim government is based, causing material damage.
The explosion happened as UN envoy to Libya Bernardino Leon was in a meeting with interim Prime Minister Abdallah Al-Thinni. The Libyan government believed that the attack aimed at undermining UN efforts to bring peace in Libya.
Libya's interim government is temporarily based in the town of Shahat, after armed militias took control of the capital Tripoli last August and forced the newly-elected parliament to base in the eastern city of Tobruk.
Libya has witnessed several attacks against foreign missions, including an attack on the U.S. mission in Benghazi in September, 2012, in which four diplomats, including ambassador Christopher Stevens, were killed.
