Inside Gaza, cut off from the world by a near total blockade, Israeli airstrikes have decimated entire neighborhoods, leveling homes, schools and mosques. CNN drone footage from Monday showed the level of destruction across parts of the strip, with whole streets flattened in the al-Rimal neighborhood in Gaza City and a row of destroyed buildings known as al-Zahra towers in central Gaza.

Save the Children said Monday that over 1 million children are “trapped” in Gaza with no safe place to go and warned of the devastating impacts of lacking medication and electricity to power vital health infrastructure in the enclave.

“At least 2,000 children have been killed in Gaza over the past 17 days, and a further 27 killed in the West Bank,” the aid agency said on Monday.

“We call on all parties to take immediate steps to protect the lives of children, and on the international community to support those efforts,” Save the Children said, adding that Israeli airstrikes are “killing and injuring children indiscriminately.”
