Eye witnesses have reported that a bomb has exploded outside the United Arab Emirates (UAE) and Egyptian embassies in the Libyan capital Tripoli.
According to Reuters, there are no immediate reports of any casualties or major damage and it was not clear whether the embassies had actually been hit, although some surrounding buildings were affected.
However, both Egypt and UAE officials are said to be pulling out diplomatic staff after a series of bomb blasts.
Libya has been beset with bombings over the last month. On 12 November a car bomb exploded in the eastern Libyan city of Tobruk, where the country's elected parliament is based.
It is believed that at least three people died in the attack.
The United Nations High Commission for Refugees revealed last month that around 100,000 Libyan civilians have fled fighting in the Libyan capital of Tripoli following continual violence and political instability.
The UNHCR also estimated around 287,000 people in 29 towns and cities had been displaced in Libya, with fighting among armed rebel groups intensifying.
