On Friday, the Israeli occupation army bombed hospitals in Gaza and imposed a siege on a number of them, and while medical facilities are unable to care for the injured and sick, the International Red Cross said that the status of the health system in the Strip has reached the point of no return.

Many hospitals, especially the Shifa Medical Complex, are now in the crosshairs of Israeli fire after the incursion of Israeli tanks into some neighborhoods of Gaza.

Al-Jazeera correspondent reported that Israeli artillery shelling targeted this evening the vicinity of Al-Shifa Hospital, west of Gaza City.

Earlier today, the Israeli occupation forces shelled the clinic building in Al-Shifa Hospital, which shelters thousands of displaced people, killing 13 people, according to the government media office in Gaza.

In a previous interview with Al Jazeera, the director of hospitals in the Gaza Strip, Mohammed Zaqout, warned that the occupation is preparing for the largest massacre against Shifa Hospital, which was targeted 5 times, pointing out that the dangers do not beset the Shifa complex alone.

This comes as the IDF continues to repeat its claims that Hamas operatives are carrying out attacks from al-Shifa Hospital and other hospitals in the Gaza Strip.

Hamas has denied the allegations, and international organizations such as Human Rights Watch have confirmed that there is no evidence to do so.

The World Health Organization (WHO) said health workers in Gaza said there was intense violence around Shifa Hospital.

For its part, the Palestinian Red Crescent said that snipers from the occupation forces targeted Al-Quds Hospital, killing one person and wounding 28, most of them children.

The director of hospitals in Gaza, Mohammed Zaqout, told Al Jazeera that communication with al-Quds hospital had been cut off because of Israeli shelling.

The Israeli army is also imposing a siege on Al-Nasr Children's Hospital in Gaza for a fourth day.

At dawn today, Israeli shelling targeted the Rantisi Children's Specialized Hospital, which led to a large fire in the basement of the facility and some of its facilities.

Mustafa al-Kahlout, director of al-Rantisi Hospital, told Al Jazeera that the Israeli army has been besieging the hospital since yesterday.

The Indonesian hospital in the northern Gaza Strip was also bombed yesterday evening.

Catastrophic situation

Meanwhile, the International Red Cross confirmed that the situation of the health system in the Gaza Strip has reached the point of no return with the depletion of fuel and supplies and power cuts.

The Red Cross said the lives of thousands of civilians, patients and medical staff in Gaza were at risk under this situation, calling for the protection of patients and medical care workers amid escalating attacks on medical facilities.

In statements to Al Jazeera, the director of Al-Shifa Medical Complex, Mohammed Abu Salmiya, described the current situation to Al Jazeera as tragic, saying that today was a day of war on hospitals in Gaza.

Ashraf al-Qidra, spokesman for Gaza's Health Ministry, told Al Jazeera that ambulances were unable to work amid ongoing Israeli targeting.

Al Jazeera's correspondent reported a power outage at the Indonesian hospital in the northern Gaza Strip after fuel stocks ran out.

The Palestinian Red Crescent said that Gaza's hospitals are in a catastrophic situation, with no water or food provided to the sick and displaced.

The Ministry of Health in Gaza confirmed that 21 hospitals and 47 health centers in the Gaza Strip were out of service, noting that fate awaits other hospitals due to the depletion of fuel and power cuts.

She added that hospitals in the Gaza Strip have critical hours ahead as a result of the lack of entry of fuel and the deliberate targeting by the Israeli occupation forces.
