More than 100 charity and human rights groups say Israel’s blockade and ongoing military offensive are pushing Palestinians in the Gaza Strip toward starvation. Israeli strikes meanwhile killed another 21 people overnight and into Wednesday, according to local health officials.

Israel denies that it is responsible for hunger in Gaza. It called the countries’ statement “disconnected from reality” and blamed Hamas for undermining aid distribution and failing to agree to a ceasefire.

Humanitarian aid agencies are warning that their staff inside Gaza are starving alongside the civilians they are trying to help
