Israeli forces hit the city of Jenin with drone strikes during an overnight operation on Monday that left at least seven people dead.
The Palestinian health ministry confirmed at least seven people had been killed and 27 wounded in Jenin, while another man was killed in the city of Ramallah after being shot in the head at a checkpoint.

A spokesman for Palestinian President Mahmoud Abbas called the operation "a new war crime against our defenceless people".
