STORY: Plumes of smoke were seen rising above the skyline of Gaza's Khan Younis on Monday (October 20) as a fragile ceasefire held despite violations over the weekend.

In a separate incident, Israeli fire killed three people near a ceasefire line in Gaza, medics said, with U.S. envoys expected in Israel to try to push forward the fragile truce that faced its gravest test so far over the weekend.

The incident, in the Gaza City suburb of Tuffah, was the latest along the "yellow line" demarcating Israel's military pullback inside Gaza from the main populated areas, stoking new fears among Gaza residents.

Local health authorities said Israeli tank fire had killed three people. The Israeli military said forces had fired at militants who crossed the yellow line to remove the threat.

Gaza City residents said they were confused about where the line runs, with electronic maps available but physical markings yet to be established along most of the route.

A Palestinian official close to ceasefire talks said efforts by Arab mediators and the United States would be stepped up on Monday, after helping restore calm in the enclave following a day of intense bombardment that killed at least 28 people.

Israel said it launched the strikes across the enclave on Sunday in response to a Palestinian attack that killed two soldiers who were operating within the agreed deployment line in Rafah, in southern Gaza, in what it described as a blatant violation by Hamas of the truce.
