President Donald Trump signalled Friday to reporters that Israel should escalate its offensive in Gaza, accusing Hamas of not wanting a ceasefire deal following months of negotiations.

New ground and air offensive comes after dozens of Palestinians seeking aid were killed in one of the deadliest incidents in months.

Naeema, a 30-year-old Palestinian mother, carried her malnourished 2-year-old son, Yazan, in their damaged home in the Al-Shati refugee camp on July 23. The World Food Programme said nearly one in three people in Gaza are not eating for days at a stretch and "thousands" were "on the verge of catastrophic hunger."

Israel over "drip feeding" of aid to Palestinians and say "the war in Gaza must end," just as it looks set to expand.

Doctors and aid workers inside Gaza are reporting the highest levels of malnutrition in children they have ever seen as the hunger crisis reportedly continues to worsen.

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.

Over 100 aid groups warn of mass starvation in Gaza, urging a ceasefire and unrestricted aid access. More Videos. Trump accuses Obama of treason in attacks over 2016 Russia probe
