Tunis: The European Union’s foreign policy chief has unveiled a 100 million euro ($109 million) aid package for Libya’s fledgling unity government one day after an attack by a suicide bomber killed at least 60 policemen.

Federica Mogherini announced the aid deal Friday at a joint press conference with Libyan Prime Minister Fayez Sarraj in Tunis, the capital of neighboring Tunisia, where the unity government is temporarily based.

Mogherini condemned Thursday’s mass killing of officers and called security “the greatest challenge Libya faces.”

An affiliate of Daesh group in eastern Libya claimed responsibility for the attack in Zliten, when an attacker detonated a truck bomb beside a police training center.

Mogherini, who spent Friday in talks with senior Libyan officials, said EU nations would offer Libya “technical and logistical” support for battling extremists, but no troops on the ground.

Libya slid into chaos following the 2011 toppling and killing of dictator Muammar Gaddafi. The oil-rich country long has been torn between an Islamist government based in the capital, Tripoli, and a rival United Nations-recognised administration in eastern Libya. The unity government, forged last month following UN-led negotiations, is currently based in Tunis because of security risks back home.

Analysts say these divisions are bolstering the position of Daesh

“The situation has become very worrisome... with Daesh taking advantage of the chaos, the collapse of the central authorities and wars by proxy,” said Karim Bitar, head of research at the French Institute of International Relations.

The international community has been pleading for months with Libya’s rival parliaments to embrace the UN-brokered deal.

Mogherini said she had “fruitful and concrete” talks with Libyan politicians on how the EU can help the future government in the “fight against terrorism and namely against Daesh”.

“The best response to terrorism especially to Daesh will be a Libyan response” and a government to unite Libyans, she said, adding that the EU could help provide “training and advising”.

UN Secretary General Ban Ki-moon condemned Thursday’s attacks and also urged unity among Libyans, while the UN Security Council called on the country’s rival groups to speed up the formation of a unity government.

Bitar said the establishment of a national unity government was a matter of “urgency” but he warned international efforts could fail due to “numerous suspicions” on the ground.

Mohamed Eljarh, a non-resident fellow with the Atlantic Council’s Hariri Centre, agreed.

He said the latest attacks claimed by Daesh “would not end the feud in Libya, but could at best result in reducing the trust deficit between the various armed and political groups as they attempt to cooperate and help each other in the face of Daesh’s expansion”.

The chaos in Libya since 2011 has led to its rise as a stepping stone for migrants crossing the Mediterranean to Europe.

The Daesh offensive against the oil terminals in Ras Lanouf and nearby Al Sidra in Libya’s so-called “oil crescent” have, meanwhile, come as the terrorist group has tried for weeks to push east from its stronghold in Sirte.

Officials have warned the already crumbling state could be paralysed if Daesh, which is reported to have at least 3,000 fighters in Libya, seizes control of oil resources.
