The UN has demanded Israel allow a 'flood of aid' into Gaza as it warns of 'atrocious levels of death and destruction.'

The UN secretary-general Antonio Guterres said the prohibition of key supplies and strict quotas are being unnecessarily imposed.

Mr Guterres said: 'All the aid authorised until now amounts to a teaspoon of aid when a flood of assistance is required.

'The needs are massive and the obstacles are staggering.'

He said there are 9000 trucks of supplies being held as only small levels of aid have been allowed into the country following Israel's 11-week-long blockade on food, fuel, water and medicine.
