Israel-Gaza live updates: Israel 'deepening the war' in Gaza: Netanyahu

The Palestinian Islamic Jihad released a video on Tuesday of two Israeli hostages pleading for their release.

The men -- who identified themselves as Gadi Moses and Elad Katzir -- spoke as they appeared in front of a plain background in the nearly 2 1/2-minute video.

"I want to convey to my friends and supporters that we must increase the pressure so that the government understands what we want," Moses said in the video provided by the hostage-takers. "We want every effort to be made so that we will soon arrive back home to our friends, our family, to our home."

Addressing Israeli leaders, including Prime Minister Benjamin Netanyahu and Israel Defense Forces Commander Hertzi Halevi, Moses said he feared being killed by an Israeli bomb.

"This situation where we could die at any moment is an unbearable situation; there is a reasonable chance that we will also be killed tonight," he said.

Katzir, 47, also said the bombings "endanger our lives" and urged Israeli leaders to make a prisoner exchange deal.

"We don't want to die in Gaza," he said. "We want them to do whatever it takes to bring us home."

It is unclear when the video was recorded and if the men were told what to say.

The hostages' families gave ABC News permission to use stills from the video.

The Israel Defense Forces said it’s found about 1,500 tunnel shafts and underground passages in Gaza since the start of the war.

The IDF -- which has consistently accused Hamas of using civilians in Gaza as human shields -- said most tunnels were under schools, hospitals, mosques, United Nations facilities and civilian institutions.

Forty trucks carrying commercial goods crossed into the Gaza Strip on Tuesday -- the first time commercial goods entered since the war began, Palestinian border crossing spokesman Wael Abu Omar told ABC News.

The trucks -- carrying items including flour, oil and salt -- entered through Israel’s Kerem Shalom crossing, the spokesman said.

Israeli President Isaac Herzog said Tuesday that “Israel is ready for another humanitarian pause and additional humanitarian aid in order to enable the release of hostages.”

Herzog said to achieve this, “the responsibility lies fully with [Hamas leader Yahya] Sinwar and the leadership of Hamas.”

“It is really important for us to reiterate -- we are not fighting the people of Gaza. They are not our enemies,” the president said. “We are fighting Hamas, they are the enemy. And in this respect, we are taking all possible humanitarian steps according to international humanitarian law.”

Herzog said the amount of humanitarian aid for hard-hit Gaza “can be tripled instantaneously.”

“For the last two weeks, Israel has operated new scanning equipment in [the Israeli city of] Nitzana enabling the entry of 350 trucks a day. For the last two weeks there was a failure by the United Nations predominantly, and other partners, in the inflow of trucks into Gaza -- only about 125 or 100 trucks a day,” he said. “You can triple the amount of trucks easily, if there was only an effort by the United Nations and its partners. The world has to know that you could have had tens of thousands of tons a day more going into Gaza.”

A UNRWA spokesperson disputed Herzog's claim, saying, "That’s not at all accurate."
