The Head of the UN Support Mission to Libya (UNSMIL) told the Human Rights Council on Wednesday that impunity must be challenged, and all grave violations must be punished accordingly.

"Sanctions must be imposed and perpetrators must be brought to the national courts or the International Criminal Court." Ghassan Salame remarked.

Salame added in his statement to the UN Human Rights Council that UN's sanctioning of six human traffickers was a good first step but must be followed by others.

Salame added that armed groups loyal to the "Government of National Accord" and Khalifa Haftar's self-proclaimed army continue to violate the International Humanitarian Law and human rights and use foreign mercenaries, especially in south Libya.

"Tripoli clashes resulted in 120 dead, 400 injured, 5.000 displaced, abductions and looting that underline consequences of lawlessness." Salame said.

"We have pushed for concrete and balanced steps to build the state security institutions, in a credible timeline. We are encouraging the Libyan authorities to revise the security arrangements in Tripoli to undo this intolerable and unsustainable status quo." He added.

Salame also indicated that terror attacks on the rise in Libya with 57 dead in 14 attacks since the beginning of this year, including the latest attack on the National Oil Corporation in Tripoli.

"UNSMIL ready to back appointment of a special rapporteur on Libya." He added.
