The Libyan Crimes Watch (LCW) has condemned the killing of Ibrahim Al-Nalouti, his wife, and 17-year-old son, who were shot dead in the head by masked gunmen.

The armed group stormed Al-Nalouti's home in the Al-Dhahra neighborhood in Tripoli last Tuesday.

In a statement on Monday, the organization called for a serious and effective investigation to uncover the perpetrators and bring them to justice, stressing that such crimes must not go unpunished.

The 54-years old Al-Nalouti was the head of Change Leaders Organization for Peace and Development and a researcher at the Libya Center for Strategic and Future Studies.
