Several detainees' institutions, including the Commission of Detainees and Ex-Detainees Affairs, and the Palestinian Prisoner's Society held the Israeli occupation authorities fully responsible for the death of Abdo al-Tamimi, who died last night while being held in the Russian compound detention and interrogation center, known as al-Maskubiyya, in Jerusalem.

Forty-three-year-old Tamimi, from Shufa’at refugee camp in occupied Jerusalem, was detained last Sunday over a traffic violation.

The Tamimi family said Israeli police contacted them last night and informed them that Abdo died of a heart attack inside his cell at al-Maskubiyya, an interrogation center known for its brutal use of torture.

However, the detainees’ institutions refuted the Israeli allegations that he died of natural causes and indicated that his family confirmed, according to information from inside the al-Maskubiyya, that their son was beaten and brutally assaulted moments before his death was announced.

A number of his family members were reportedly detained by Israeli police after they went to inquire about his death.

An autopsy will be performed on Tamimi’s body to determine the circumstances behind his death.

Tamimi has four children and his wife is pregnant.
