Israeli occupation authorities released all suspects detained s part of a probe into the firebombing of a Palestinian home that burned to death an 18-month-old child and his father.

"All those arrested yesterday for interrogation have been released," a spokeswoman for the Shin Bet security agency told AFP, without providing further details.

They did not provide the number of those detained in the raids early Sunday in wildcat Jewish settlement outposts in the West Bank near the Palestinian village of Duma, where the brutal firebombing occurred.

Wildcat outposts in the Israeli-occupied West Bank are notorious for housing Zionist settlers, referred to as hilltop youth.

The Palestinian family's small brick and cement home in Duma was gutted by fire early on July 31, and a Jewish Star of David spray-painted on a wall along with the words "revenge" and "long live the Messiah".

The arson attack on the family's home in the occupied West Bank that killed 18-month-old Ali Dawabsha and his father, Saad sparked an international outcry over the ongoing Israeli crimes against Palestinians.

Mother Riham and four-year-old son Ahmed were also in an Israeli hospital, where a spokeswoman described their condition last week as life-threatening.
