The Israeli magistrate court extended the detention of 12-year-old Muhammad Ismail Hushiyeh for a year on Wednesday, according to the head of the Jerusalem Committee for Families of Prisoners.
Amjad Abu Asab told Ma'an that Hushiyeh would be detained in a juvenile facility in the town of Ablin in northern Israel.
Hushiyeh is the youngest Palestinian prisoner from Jerusalem held by Israeli authorities, Abu Asab said.
The 12-year-old was detained in late January for alleged involvement in a stab attack against an Israeli settler after Israeli forces reported he was in possession of a knife.
There are currently ten Palestinian children from Jerusalem under the age of 14 being held in Israeli juvenile facilities, according to Abu Asab.
According to the prisoners' rights group Addameer, there are currently 438 Palestinian children held in Israeli prisons.
More than 200 Palestinians and almost 30 Israelis have been killed since the beginning of a wave of violence in October, characterized by a number of small-scale Palestinian attacks and alleged attacks against Israeli military targets.
The number of Palestinian and Israeli deaths saw a dramatic drop over the last two months, with the Israeli leadership suggesting its severe security measures were responsible for the emerging trend.
However, the Palestinian Center for Policy and Survey Research found in a poll last month that support for stabbing attacks had seen a decline in the West Bank in recent months -- "due, it seems, to a rising perception in its inefficacy."
