The United Nations Children's Fund (UNICEF) said on Thursday that children in Gaza are the most affected by the war, stressing the need to protect them.

UNICEF Executive Director Catherine Russell said that the situation in the Gaza Strip is "frightening" and that war always has very bad consequences for children.

Speaking to CNN, Russell stressed that it is not possible to accept the death of children from starvation after they were displaced and lost their parents.

She added that the two main issues that make the distribution of humanitarian aid difficult are the lack of security and lack of access to those in need.
