Israeli police shot dead a Palestinian woman and her teenage brother on Wednesday, saying they were armed with knives and tried to carry out an attack at a checkpoint in the occupied West Bank.

Witnesses told Ma’an that 23-year-old Maram Salih Hassan Abu Ismail, five months pregnant, and her 16-year-old brother Ibrahim were en route to Jerusalem when they took a path intended for vehicles, not pedestrians, into Qalandiya checkpoint near Ramallah. The two were apparently unable to understand Israeli officers yelling in Hebrew, and stopped walking.

Witnesses said it appeared that Ibrahim attempted to grab his sister’s hand and move away from the officers, when they opened fire on her. Maram fell to the ground and when Ibrahim attempted to aid her, he was shot in his tracks.
