Israeli fire has killed at least six Palestinians, including two children, in separate incidents across Gaza, local health officials said, in the latest violence to undermine the US-brokered ceasefire agreement.
Four people, including a young child, were killed in a strike that targeted a police vehicle in Gaza city, the Hamas-run Interior Ministry said.
A police officer was among the dead, while nine bystanders were wounded, some critically, it said.
In the north of the enclave, near Jabalia, Israeli fire killed three-year-old Yahya Al-Malahi, health authorities and his family said.
Israel's military did not immediately provide comment on either incident.
In northern Gaza, Israel's military said it killed a man who had approached the armistice line with Hamas, describing him as an armed militant.
Health authorities confirmed a man had been killed in the area, without providing details.
The ceasefire that began last October halted two years of full-blown war but left Israeli troops in control of a depopulated zone that makes up well over half of Gaza, with Hamas in power in the remaining, narrow coastal strip.
Israel has escalated its attacks on Hamas-led police and security forces since October, killing dozens, the group's officials in Gaza have told Reuters, accusing Israel of trying to cause chaos and anarchy.
Israel says it aims to thwart attacks by Hamas and other militant factions.
More than 750 Palestinians have been killed since the ceasefire deal took effect, while militants have killed four Israeli soldiers. Israel and Hamas have traded blame for ceasefire violations.
Palestinians also say Israeli forces have been expanding the zone they occupy. Israel denies this.
