Israel and Hamas continue to trade accusations of near-daily ceasefire violations, keeping the Gaza Strip locked in bloodshed months after a truce took effect in October.

"We just transported four martyrs and more than 17 wounded following an Israeli airstrike that targeted a police station in the Al-Noss area of Al-Mawasi district in western Khan Yunis," the civil defence agency, which operates as a rescue force under Hamas, said in a statement.

The Gaza police directorate confirmed that Israeli warplanes struck the police station in Khan Yunis. Nasser Hospital in the area said it received five bodies of people killed in the attack.

The Israeli military said it was looking into the reports.

In a separate incident, Israeli naval forces shot dead a fisherman in the early hours of Sunday, Al-Aqsa Hospital in Deir el-Balah said after receiving his body.

Sunday's bloodshed followed a deadly Saturday in which at least 12 people died across Gaza, including a man the Israeli military identified as a Hamas "terrorist cell commander".

At least 961 Palestinians have been killed since the ceasefire took effect on October 10 last year, according to Gaza's health ministry, which operates under Hamas authority and whose figures are considered reliable by the United Nations.

The Israeli army has reported five deaths in its ranks during the same period.

Restrictions imposed on media outlets and limited access in Gaza prevent AFP from independently verifying tolls or freely covering the violence there.
