ISRAELI troops killed at least three Palestinians in Gaza today despite the ceasefire that came into force a week ago.

A senior Hamas official told Reuters that Israel has shot and killed at least 24 people since last Friday.

The unnamed official said the Israelis were “working day and night to undermine the ceasefire deal.”

Israel has not immediately responded to the accusations.

In recent days, Israel has accused some Palestinians of ignoring warnings not to approach Israeli ceasefire positions and said troops “opened fire to remove the threat.”

But a rights group formed by veterans of Israel’s armed forces has blasted Israeli troops for shooting civilians in Gaza for their supposed crossing of the “yellow line” behind which Israel’s military has redeployed.

Breaking the Silence, which monitors abuses of Palestinians in the occupied territory, said civilians are being shot and killed in Gaza for “crossing a line they don’t even know exists.”

Posting on social media, the group said: “Let’s be clear. That line exists only on a map, not on the ground.

“The same rules of engagement we’ve seen near the Gaza Humanitarian Foundation ‘aid sites’ and across the Strip: ‘no-go zones, cross them, and you get shot,” it said.

The group said: anyone who enters a “no-go zone” is automatically “sentenced to death.”

The Gaza Health Ministry said the death toll of Palestinians killed by Israel’s invasion of Gaza now stands at 67,967 and 170,179 wounded.

Desperately needed humanitarian aid for Palestinians is still failing to reach the enclave.

Israel warned today that it would keep the Rafah crossing closed and reduce aid into the Palestinian territory as, it said, Hamas was returning the bodies of dead hostages too slowly.

The Co-ordinator of Government Activities in the Territories, the arm of the Israeli military that oversees aid flows in Gaza, claimed humanitarian aid was entering the territory via the Kerem Shalom crossing with Israel, and at other crossings.

Hind Khoudary, an Al Jazeera journalist reporting from Deir el-Balah in Gaza, said: “We are supposed to be receiving 600 trucks every day of humanitarian aid, but what’s entering is less than 300 trucks.

She said that in the main “what is entering are commercial trucks and things that are being sold in the market. But Palestinians do not have the ability to buy these items. Gaza residents do not have money.”
