The Israeli military says guards have shot and killed a Palestinian woman who drew a knife as she attempted to attack them at a West Bank checkpoint.

Defense Ministry spokeswoman Arielle Heffez says the woman ignored warning shots and calls to stop as she approached the checkpoint on Monday.

The Israeli army says troops are looking for another person suspected of involvement in the attack but provided no details. Israeli media are reporting the woman allegedly left a suicide note.

Since mid-September, 12 Israelis have been killed in Palestinian attacks, mostly stabbing assaults. Meanwhile, 75 Palestinians have been killed by Israeli fire, including 48 said by Israel to be involved in attacks or attempted attacks. The other Palestinians were killed in clashes between stone throwers and security forces.
