Israel has declared a “complete siege” on the Gaza Strip territory, saying electricity, food, fuel and water would be cut off.
According to residents, aid has not reached the enclave since Saturday, as Israel responds to the Hamas attacks.
The area, which is ruled by Hamas militants but Israel controls the airspace and its shoreline, is home to about 2.3 million people in total – 80% of whom rely on humanitarian aid mainly due to the ongoing hostilities with Israel.
Nearly 700 people have died in these attacks and thousands more are reported to have been injured.
The US says it is moving an aircraft carrier, ships and jets to the eastern Mediterranean and will also give Israel additional equipment and ammunition.
