World Health Organization has also warned that health system in Gaza is now at breaking point and there is little time to prevent humanitarian catastrophe.

In a statement, WHO called for an end to hostilities and protection of health care and civilians.

Meanwhile, Human Rights Watch has accused Israel of using white phosphorus munitions in its military operations in Gaza and Lebanon.

In a statement, the international human rights organization said the use of such weapons puts civilians at risk of serious and long-term injury.

Human Rights Watch said it has verified videos taken in Lebanon and Gaza showing multiple airbursts of artillery-fired white phosphorus. Reuters..
