JERUSALEM — Israeli police said they do not believe an arson attack on a Palestinian home Sunday was carried out by Jewish attackers. The house that was set ablaze belonged to a key witness to an arson attack by Jewish perpetrators that killed a Palestinian toddler and his parents last year.

Palestinian officials say attackers broke the bedroom window of Ibrahim Dawabsheh’s home and set the house on fire. Dawabsheh and his wife escaped. He was unharmed but his wife suffered from light smoke inhalation.

Dawabsheh, a relative of last year’s victims, is a witness to the attack that killed them and is currently testifying before an Israeli court in the trial of two Jewish extremists.

Last July, suspected Jewish settlers hurled firebombs into a home, killing 18-month-old Ali Dawabsheh. His mother, Riham, and father, Saad, later died of their wounds. Ali’s 4-year-old brother Ahmad survived.

Ibrahim Dawabsheh told Israeli Channel 10 TV News, “the minute I saw the fire, I was reminded of Saad’s family, of course.”
