The European Union on Monday expressed "deep concern" over recent developments in Libya after armed groups launched attacks on Tripoli's parliamnet and an eastern airbase.

The violence in Libya has left nearly 80 people dead and more than 140 injured, Agence France Presse (AFP) reported. Speaking to the news agency, witnesses reported that those behind the attacks on the parliament in Tripoli belong to the Zintan brigades, known for their fierce opposition to Islamist groups and have attacked parliament before.

A spokesperson for the European Union (EU) foreign affairs chief Catherine Ashton said the organization was concerned about the "continuing deterioration" of stability in the north African country, according to AFP.

“The EU renews its commitment to support the Libyan people...and calls on all parties to build consensus so as to ensure a transition to a stable democracy,” spokesman Michael Mann said, AFP reported.

Several EU member states - including Italy who once colonialized Libya - are also reportedly growing worried over the increase of refugees entering Europe from Libya that has been sparked due to the recent unrest.
