UNITED NATIONS/GENEVA (Reuters) -Famine is "playing out" in the Gaza Strip, a global hunger monitor said in an alert issued on Tuesday as international criticism of Israel intensifies over rapidly worsening conditions in the Palestinian enclave.

Ministers have been called back to Westminster on Tuesday to discuss peace plans and aid efforts for the territory.

"President Trump wants to alleviate suffering for the people of Gaza because he has a humanitarian heart. He announced a new aid plan today to help Gazans obtain crucial access to food – details are forthcoming," White House deputy press secretary Anna Kelly said in a comment to ABC News.

U.N. Secretary General Antonio Guterres called Monday for and end to the war in Gaza and the implementation of a two-state solution at a high level conference in New York.

A pair of leading Israeli human rights groups has accused Israel of “committing genocide against Palestinians in Gaza,” becoming the first such organizations to make the claim.

A newborn died Monday afternoon, hours after she was delivered in a surgery following the killing of her mother in Gaza Strip, a hospital said.

Israel has announced a daily “tactical pause in military activity” in three areas of Gaza to enable more aid to reach people, amid growing international outrage over starvation in the territory.
