A car bomb went off early Thursday outside the Egyptian embassy in Tripoli, causing some damage to the building but no injuries.

A Libyan security official told the Associated Press news agency that shortly after the blast, another car bomb was discovered near the embassy of the United Arab Emirates. It is unclear why that car bomb did not explode.

Both embassies, along with most diplomatic missions, foreign and international organizations have been closed for months as Islamist-allied armed groups seized Tripoli after weeks of fierce fighting.

The blasts followed a series of car bombs on Wednesday mainly in towns under the control of the internationally recognized government, which based in the eastern city of Tobruk.

A Reuters news agency witness said the Egyptian embassy bomb had slightly damaged buildings and some stores, but it was not clear if the embassy had been hit.

Three years after the fall of Muammar Gaddafi, Libya is caught up in growing unrest as rival armed factions compete for power and control of the OPEC country’s oil resources.

One faction has taken over Tripoli, setting up its own government and parliament and forcing the elected parliament and administration of Prime Minister Abdullah al-Thinni to operate out of Tobruk.

According to Al Jazeera, rivals of Thinni’s government say neighboring Egypt “has lent support to a renegade former Libyan army general, Khalifa Haftar, who is leading a campaign to drive armed factions out of the eastern city of Benghazi. His foes say he has received air support from Egypt, which is worried about the spread of fighters alligned with radicals.”

International efforts led by the United Nations to mediate between the rival factions have so far failed to broker a ceasefire.
