Israeli forces killed three Palestinians in Gaza near the line demarcating areas of Israeli control on Monday, underlining the struggle to broaden a fragile ceasefire deal approved over six weeks ago to global acclaim.

Palestinian medics said Monday¡¯s incidents involved an Israeli drone firing a missile at a group of people east of Khan Younis, killing two and wounding another, and a tank shell killing a person on the eastern side of Gaza City.

Israel¡¯s military said it had fired after identifying what it called ¡°terrorists¡± crossing what is known as the yellow line and approaching its troops, posing an immediate threat to them.
