Tripoli, Aug 18 (IANS): An unidentified warplane Monday bombed Islamist militants in Libya's volatile capital Tripoli, killing five people and injuring several others, according to sources.

The fighter jet launched airstrikes on some camps near the airport highway in Tripoli where one Islamist armed group from Misrata was based, Xinhua reported citing Alaa Dweik, spokesperson of the militant group Central Libya Shield.

Dweik added that five militants were killed and the injured had not been counted. The Tripoli Medical Centre and Mitiga hospital also confirmed that they received a number of injured after the airstrikes.

It is not immediately clear about the identity of the warplane, and media reported that none of the warring militia groups in Tripoli have such powerful warplanes.

One Libyan TV channel claimed that the warplane belonged to the Italian Air Force, but later Italian Ambassador to Libya Joseph Jerima denied Italy's involvement in the incident.

Since July 13, clashes between Islamist armed groups and pro-secular militias in Tripoli have left at least 102 people dead and 452 others wounded.

Meanwhile, in eastern Benghazi, fierce fighting continued between the army and Islamist militant groups, who are now in control of most of the city.

As the clashes intensified, a number of countries have evacuated their citizens from Libya.
