As the war in Gaza intensifies - the Israeli army says 21 of its soldiers have been killed in combat in one of its bloodiest for military casualties - the focus of the conflict has shifted to the town of Khan Younis.

Dozens of Palestinians were reportedly killed as hospitals, ambulances and schools 鈥� where thousands of civilians are sheltering 鈥� were targeted.

Juliette Touma - the Director of Communications at the United Nations Relief and Works Agency for Palestine Refugees in the Near East (UNRWA) - has just returned to Jordan from inside Gaza.

She told Newsday what she witnessed while there.

"People are exhausted and do not have medicine for chronic diseases. Internally displaced people have set up basic structures everywhere. A mother living in one of these structures told me the only food she and 26 members of her family had was a piece of vegetable for the coming few days.鈥�
