The Israeli army killed six Palestinians in the Gaza Strip in two separate incidents on Wednesday, marking the latest breach of the cease-fire agreement.

A military statement claimed that six people were hit in eastern Rafah after they "most likely emerged” from an underground infrastructure in the area.

The army added that four of them were killed and two others detained.

According to Israeli media, nearly 200 Hamas fighters are trapped in underground tunnels in Rafah, which lies inside areas still occupied by Israeli troops as part of the "yellow line” arrangements under the ceasefire deal that took effect on Oct. 10.

Tel Aviv has not responded to demands from the Palestinian group and mediators to allow them safe passage to areas not controlled by Israel inside Gaza.
