Five Palestinians, including a 60-year-old woman, were killed by Israeli forces in Jenin over the past 24 hours, the Palestinian Authority said on Tuesday, adding to a growing toll from one of the largest operations seen in the West Bank in years.

The fragile ceasefire has held since it began on Jan. 19, even as Israeli strikes have killed dozens of Palestinians. Israel says it has struck Palestinians who approached its troops, entered unauthorized areas or otherwise violated the terms of the truce.
