A Libyan father slit the throats of his three teenage daughters in a horrible act of honor killing after he learnt that Moammar Gadhafi's fighters had raped them, an aid group says.

The murders took place in Tomina, on the outskirts of Misrata, the port city that was besieged by Gadhafi loyalists. The father slit the throats of unnamed daughters aged 15, 17 and 18 after they were raped by the soldiers, according to a report by Physicians for Human Rights.

In many Muslim countries, women are routinely victimized for the guilt of undergoing a heinous crime. The PHR report says widespread human rights violations took place in Misrata which was besieged by Gadhafi's forces for two months.

The report confirms fears that prevailed earlier that pro-Gadhafi forces had unleashed a range of cruelties on defenseless people. Children were placed on tank tops as human shields and girls as young as 14 years of age were raped, the report said.

One witness reported that (Gadhafi) forces transformed an elementary school into a detention site where they reportedly raped women and girls as young as 14 years old, the report said, according to the Daily Mail.

The PHR report also says pro-Gadhafi forces committed crimes like summary killings, hostage-taking and the use of mosques, schools and marketplaces as weapons depots.

“Four eyewitnesses reported that Gaddafi troops forcibly detained 107 civilians and used them as human shields to guard military munitions from NATO attacks south of Misrata, the report says.

Moammar Gadhafi, his son Saif al-Islam and brother-in-law and intelligence chief Abdullah al-Sanussi are wanted by the International Criminal Court in The Hague on charges of war crimes.

It was reported earlier that the Khamis Brigade, the fierce band of fighters led by another Gadhafi son, Khamis, had killed around 50 detainees and then set the Tripoli warehouse where they were lodged on fire on Aug. 23. A similar incident was reported on Aug. 21, when the Khamis Brigade killed 17 detainees in a makeshift prison near Gargur in Tripoli. In another incident, on Aug. 26, 18 decomposed corpses were also found near the Internal Security building in a dried riverbed between Gargur and Bab al-Aziziya, opposite the brigade headquarters.
