A senior Libyan Interior Ministry official says two suspects have been arrested in connection to twin car bombings in an eastern city where a U.N. envoy was meeting with the prime minister.

Neither U.N. envoy Bernardino Leon nor Libyan Prime Minister Abdullah al-Thinni were targeted in the bombings in the eastern city of Bayda on Sunday.

The two suspects are from the eastern city of Darna, where Islamic extremists pledged allegiance to the Islamic State group last month, the official said Monday.

The official says the bombings are part of series of attacks aimed at destabilizing Bayda, where the Cabinet convenes, and the far eastern city of Tobruk, where the elected parliament meets.

He spoke on condition of anonymity because he was not authorized to speak to the press.
