The United Nations Security Council was set to meet on Tuesday to discuss the war in Gaza and the hostages held by Hamas as the humanitarian crisis in the territory shows little sign of abating and cease-fire talks have stalled.

Gideon Saar, the Israeli foreign minister, told reporters on Monday that Israel had called for a meeting focused on the hostages after Hamas released videos over the weekend showing two emaciated Israeli captives. Israel says it believes that there are still about 20 living hostages in Gaza, as well as the bodies of 30 others.

The Security Council will convene as the widespread humanitarian crisis in Gaza continues after nearly two years of war between Israel and Hamas. Scores of Palestinians have died from malnutrition-related causes, according to the Gaza ministry of health. Nearly 40 percent of the population are not eating for multiple consecutive days, according to the U.N. World Food Program.

Many aid agencies and countries, including a number of Israel’s traditional allies, have blamed Israeli policy for the situation, including its blockade from March to May on aid entering the territory. Some countries, including Britain, Canada and France, have announced plans to recognize a Palestinian state.

More than 60,000 people in Gaza have been killed in the war, including thousands of children, according to Gaza health officials, who do not distinguish between civilians and combatants. Most of the enclave’s two million people have been displaced, often forced to crowd into swelling tent camps amid the rubble.
