The ambassadors of France, Italy, the United Kingdom and the United States have issued a joint statement to condemn the airstrikes on Derna, which they said had killed at least fifteen civilians, including twelve women and children, injuring many others.

“We offer our condolences to the families of the victims, and call for immediate humanitarian access to assist the injured and prevent further suffering in Derna.” The statement issued on Wednesday reads.

The ambassadors also condemned what they described as the horrific extrajudicial killing of 36 men in Al-Abyar district in eastern Benghazi, adding that they took notice of the announcement of the Khalifa Haftar’s self-styled army that it would open an investigation into the incident.

“We look forward to the prompt conclusion of that investigation and call on the ‘Libyan National Army’ to ensure the results are shared publicly with the Libyan people.” The statement said.

The statement explained that the four countries are monitoring ongoing acts of conflict in Libya closely, saying that those suspected of committing, ordering, or failing to prevent summary executions and torture on all sides must be fully investigated and, if found guilty, held accountable for their actions.

The statement added that the four countries will continue their efforts at the international level to pursue appropriate action against those who are complicit in violations of international human rights law and international humanitarian law.

An air attack on Derna on Monday killed 20 people – mostly women and children – and injured over 23.

Pro-Haftar TV channel Libya Al-Hadat claimed after the attack that Dignity Operation was responsible for the airstrikes, but later denied them after a wave of outrage both in the country and outside it.

Likewise, the spokesman of Dignity Operation, Ahmed Al-Mismari denied Tuesday - after nationwide condemnation and Presidential Council's announcement to report them to UNSC – taking part in the attack, blaming it on “the terrorists” inside the city.
