An armed group stormed the Tunisian consulate in the Libyan capital Tripoli and seized 10 workers, the Tunisian Foreign Ministry said on Friday, the Associated Press and Reuters reported.
The incident was a "blatant attack on Tunisian national sovereignty and a flagrant violation of international laws and diplomatic norms", the ministry said in a statement, according to Reuters.
Libyan officials were not immediately available for comment.
Tunisia is one of the few countries to keep a mission in Tripoli, which is controlled by a government not recognized by the international community.
No further details were immediately available.
