Washington, Oct 18 (IANS/AKI): Libyan activist Emadeddin Muntasser has urged the US to investigate war crimes allegedly committed by the powerful military strongman Khalifa Haftar and handed US officials 300 pages of evidence to back up the claim, the media reported.

Muntasser said he met US officials in Washington on October 10 and submitted a formal complaint and request for investigation regarding alleged war and financial crimes committed in Libya by Haftar - a US citizen - and his three sons, the Libya Observer reported.

"The complaint encompasses three volumes of more than 300 pages and lists the specific legal statutes which were violated, legal analysis, biographies of the alleged perpetrators and catalogues an overwhelming inventory of evidence of these war crimes," Muntasser said.

Haftar and his three sons Khaled, Saddam and Al-Saddiq have violated US laws including the Neutrality Act, enlistment in the foreign service as officers and laws prohibiting war crimes, genocide and torture, Muntasser said.

In August, Muntasser filed a complaint with the International Criminal Court accusing Haftar of orchestrating war crimes.
