The United Nations on Saturday ramped up appeals for a humanitarian ceasefire in Gaza after another night of ground incursions and intense bombardment by Israeli forces left healthcare facilities without electricity and civilians across the ravaged enclave virtually 'cut off from the outside world'.

Secretary-General António Guterres said: 'I reiterate my strong appeal for an immediate humanitarian ceasefire, together with the unconditional release of hostages and the delivery of relief at a level corresponding to the dramatic needs of the people in Gaza, where a humanitarian catastrophe is unfolding in front of our eyes.'
