24 October 2011 :

Fifty-three people, apparent Gaddafi supporters, seem to have been executed at a hotel in Sirte last week, Human Rights Watch said. The hotel is in an area of the city that was under the control of anti-Gaddafi fighters from Misrata before the killings took place.
Human Rights Watch called on Libya’s National Transitional Council (NTC) to conduct an immediate and transparent investigation into the apparent mass execution and to bring those responsible to justice.
“We found 53 decomposing bodies, apparently Gaddafi supporters, at an abandoned hotel in Sirte, and some had their hands bound behind their backs when they were shot,” said Peter Bouckaert, emergencies director at Human Rights Watch, who investigated the killings. “This requires the immediate attention of the Libyan authorities to investigate what happened and hold accountable those responsible.”
Human Rights Watch saw the badly decomposed remains of the 53 people on October 23, 2011, at the Hotel Mahari in District 2 of Sirte. The bodies were clustered together, apparently where they had been killed, on the grass in the sea-view garden of the hotel.
Anti-Gaddafi fighters from Misrata had held that area of Sirte since early October, according to witnesses interviewed by Human Rights Watch. On the entrance and walls of the hotel Human Rights Watch saw the names of several brigades from Misrata.
The condition of the bodies suggests the victims were killed approximately one week prior to their discovery, between October 14 and October 19, Human Rights Watch said. The bloodstains on the grass directly below the bodies, bullet holes visible in the ground, and the spent cartridges of AK-47 and FN-1 rifles scattered around the site strongly suggest that some, if not all of the people, were shot and killed in the location where they were discovered, Human Rights Watch said.
