Israeli occupation border guards Saturday shot dead a Palestinian woman approaching them with a knife at a checkpoint in the occupied West Bank after she ignored orders to stop, police said.

The Palestinian Authority's prisons ministry identified the dead woman as Ibtissam Kaabneh, a Palestinian who was arrested and sentenced to 18 months in prison by Israel in 2016.

Israeli occupation police alleged the woman kept walking towards the guards at Qalandiya crossing between Israel and the West Bank, despite repeated warnings to stop.

She was aged 28 and from Aqabat Jabr near the West Bank town of Jericho, police said.

On Friday, a 15-year-old Palestinian was killed by Israeli occupation army gunfire near Beita, south of Nablus.

And on Thursday, three Palestinians were also killed in the West Bank by Israeli security forces on a mission to arrest suspected "terrorists".

Violence in the West Bank increased in May, with at least 30 Palestinians killed in clashes with Israeli occupation forces and during alleged attacks.

That came amid a flare-up in Israeli-annexed east Jerusalem that led to an 11-day Israeli aggression against Palestinians in Gaza.

Some 475,000 Israeli settlers live in the West Bank, home to more than 2.8 million Palestinians.
