The Former ambassador of the United Kingdom to Libya Peter Millett has called for opening an investigation into the use of banned chemical weapons in Tripoli.

Millett said on Twitter that such allegations are dangerous indicators of a massive military escalation and amount to a war crime, saying the investigation into the allegations should be carried out by international experts as soon as possible.

Meanwhile, the Libyan Interior Minister Fathi Bashagha accused in a press conference on Wednesday Khalifa Haftar's forces and Russian Wagner Group mercenaries, who are fighting for Haftar on Salah Al-Deen frontline in southern Tripoli, of using nerve agents against Government of National Accord's forces and then killing them by snipers.

These accusations were confirmed by Canadian journalist Amru Salaheddine who said on Twitter that he had noticed four days ago at the field hospital on Salah Al-Deen frontline some injured fighters from GNA forces receiving medical treatment without any clear wounds. He said they had symptoms similar to those of epilepsy.

"I can confirm that Haftar's forces had used some kind of nerve agents after I have seen GNA fighters fall on the ground shivering and unable to breathe following shelling by Haftar's forces on Salah Al-Deen frontline." The journalist said.

In the meantime, the spokesman for Haftar's forces, Ahmed Al-Mismari, denied the accusations, blaming Turkey for "fabricating such accusations" and called on the UNSMIL and international stakeholders to take measures against what he called "rumors" and said their forces would welcome any international investigation of these allegations.
