Israel's security cabinet has announced measures to strip certain rights from terrorist families following two attacks in east Jerusalem, one of which killed seven people near a synagogue, AFP reports.

The day before, Prime Minister Benjamin Netanyahu promised a decisive and swift response to the attacks by two Palestinians from annexed east Jerusalem.

The security cabinet then announced measures to deprive the welfare rights of families of terrorists who support terrorism. It is noted that the council of ministers will discuss on Sunday a bill to revoke their Israeli identity cards.

The announced measures are in line with proposals by Netanyahu's far-right political partners, which allowed him to return to power in late December after the previous month's elections. They are likely to apply primarily to Palestinians with Israeli citizenship (Israeli Arabs) and Palestinians with residency status in annexed east Jerusalem.

On Friday evening, a 21-year-old Palestinian opened fire on passers-by outside a synagogue in the Neve Yaakov settlement area, killing seven people before being shot dead.

The bloodshed continued Saturday when a 13-year-old Palestinian boy shot and wounded a 47-year-old Israeli father and his 23-year-old son, an army officer in Silwan, near the walled Old City in east Jerusalem.

The boy responsible for the attack was wounded on the spot. No one has claimed responsibility for either attack.

Israeli forces are on high alert, and the army has announced that it will increase troop levels in the West Bank, while calls for restraint have grown from abroad.
