RAMALLAH: Israeli authorities on Sunday informed the family of Palestinian prisoner Imad Rajeh Sarhan, 47, from the city of Haifa in the 1948 territory, that he died in Gilboa prison after suffering a heart attack on Saturday, without providing further details about the circumstances of his death.

The Palestinian Commission of Detainees’ Affairs and the Palestinian Prisoners Society said Sarhan had been detained since Oct. 15, 2001, and was serving a life sentence.

They stated that during the early years of his imprisonment, he was subjected to prolonged interrogation and systematic torture, which caused serious and lasting health complications.

His condition deteriorated over the years, and he was repeatedly placed in solitary confinement.

The two institutions added that Sarhan suffered from chronic heart and vascular diseases and high blood pressure, and in recent years had been forced to use a wheelchair due to the severe decline in his health, while still being held in harsh conditions.
