LISA DESJARDINS: Good evening.

I'm Lisa Desjardins.

John Yang is away.

Tonight, prospects of an Israeli ground invasion into Gaza are rising.

Israeli airstrikes continued to hit Gaza as well as the West Bank, Lebanon and Syria, where the bombings put two international airports out of commission and the death toll climbs nearly 4,700 Palestinians and more than 1,400 Israelis have been killed in the conflict so far.

Sentiments about the war spilled over into the streets of world capitals today from Paris where thousands marched in a show of support for Palestinians to Berlin where large crowds gathered to support Israel and oppose antisemitism.

For more on the unfolding conflict, Leila Molana-Allen is in Tel Aviv with this report.

A warning this piece includes difficult images of war.

LEILA MOLANA-ALLEN: In the West Bank, this house of worship now bears the scars of war.

Israel says Hamas and Palestinian Islamic Jihad use this mosque in the Janine refugee camp to plan attacks.

ALI ALDAMAG, Refugee Camp Resident (through translator): The youth were round and thankfully the neighborhood outside was empty.

We heard a sound like a whistle, and then there was a strike on the roof of the mosque.

LEILA MOLANA-ALLEN: Israel also struck two mosques as a refugee camp in Gaza and two airports in Syria where numerous Iranian proxy groups operate.

Fires broke out on the northern border with Lebanon.

Israel says it struck several Hezbollah targets of the incoming missile fire.

To the south of the Egyptian Rafah Border Crossing, a second convoy of 19 aid trucks and to Gaza.

They carried humanitarian supplies, but did not appear to carry any badly needed fuel.

The UN's agency and Gaza said they would run out of fuel in three days without more and larger deliveries.

They also warned that hospitals already stretched to the limit would no longer be able to operate at all.

The Hamas run-Gaza health ministry said in a statement that the pace of aid will not change the reality of the medical response.

I put this to IDF spokesman Lieutenant Colonel Peter Lerner.

Why is it so slow for that aid to come in?

LT. COL. PETER LERNER, Israeli Military Spokesperson: So obviously it is Egypt that determines what goes in.

We are concerned that that aid will go to Hamas for it to replenish.

Rebuilt.

LEILA MOLANA-ALLEN: On Sunday evening, authorities halted the convoy after they had blasts nearby.

The Israel Defense Forces said it was accidental fire from one of its tanks.

In Israel, mourners at (inaudible) kibbutz dug 10 graves for 10 neighbors killed in the October 7 terror attacks.

GEVA MEIR, Neighbor of Hamas Victim: It's unbearable.

I have so many funerals to be in and you know, I can't even be in all the funerals you can save.

Everywhere is graves.

Everywhere is everyone is dead.

Monsters.

LEILA MOLANA-ALLEN: Forensic investigators at an Israeli morgue are still working to identify some victims.

MICHAL LEVIN-ELAD, Israeli Police's Department of National Forensic Investigations: Hundreds of bodies came every day, hundreds of bodies.

This is something we have never seen in Israel before.

LEILA MOLANA-ALLEN: U.S. forces have also seen attacks by Iran backed militias in Iraq and Syria and Houthi rebels in Yemen directed missiles towards Israel, which the U.S. shot down.

In response, the Defense Department said it would send the USS Eisenhower carrier strike group to the Persian Gulf instead of the Mediterranean Sea.

The U.S. will also send Israel additional missile defense systems and surface to air missiles.

Defense Secretary Lloyd Austin said the military has put more troops on notice to potentially deploy on top of the 2000 already received the order.

On CBS's Face the Nation, Secretary of State Antony Blinken said the U.S. has consulted with Israel about its plans for a ground invasion, but did not say whether the U.S. has asked Israel for a delay to let hostage negotiations continue.

ANTONY BLINKEN, Secretary of State: We give them our best advice.

It's important as we said, not only what they do but how they do it, particularly when it comes to making sure that civilians are as protected as they possibly can be in this crossfire of Hamas is making.

LEILA MOLANA-ALLEN: For now Israeli troops await their orders on the border with Gaza.

Tanks poised for if and when a round invasion is launched.

For PBS News Weekend, I'm Leila Molana-Allen.

LISA DESJARDINS: Late Sunday night 14 additional aid trucks crossed into Gaza from Egypt.
