Israeli Prime Minister Benjamin Netanyahu's office said on Monday that there was no cease-fire agreement ahead of the expected re-opening of an Egyptian border in Rafah.

"There is no ceasefire," the office said in a two-line statement.

Israelis residents living near the border with Lebanon will be evacuated, state officials said Monday.

People living within the 28 Israeli towns that sit within 2 km of the border will be evacuated, the Israeli Ministry of Defense's National Emergency Management Authority and the Israel Defense Forces said in a joint statement.

U.S. Secretary of State Antony Blinken on Monday reaffirmed the U.S.'s commitment to Israel "as it defends itself."

"The United States is also actively working to ensure the people of Gaza can get out of harm's way and the assistance they need -- food, water, medicine -- can get in," he said on social media. "Hamas does not care if Palestinians suffer."

The secretary is expected on Monday to travel to Israel to meet with Prime Minister Benjamin Netanyahu.

"Over the past few days, I've traveled to Israel, Jordan, Bahrain, Qatar, UAE, Saudi Arabia, and Egypt," Blinken said. "What I've heard from every partner is a shared view to prevent the conflict from spreading, to safeguard innocent lives, and to get assistance to those in Gaza who need it."

Hamas fighters are believed to be "still hiding" in some communities in southern Israel even after the Israeli military took back control, according to Israel Defense Forces spokesman Maj. Doron Spielman.

"We are in control of the communities, but we actually assume that there are Hamas terrorists that are still hiding in these areas, including in the road where we are now," Spielman told ABC News during an interview Monday in Sderot, Israel. "In all these communities, we've seen terrorist come out of hiding. Just yesterday, they took over an ambulance."

"We're still being very, very careful," he added. "This is a war zone with active terrorists that are operating here."

Sderot is a southwestern Israeli city located near the county's border with the Hamas-ruled Gaza Strip. A police station there was stormed by Hamas fighters on Saturday as part of the militant group's wider incursion, leaving at least six Israeli police officers dead. The IDF then bombed the police station with the Hamas fighters inside, demolishing it.

Hamas fighters and other Palestinian militants are "striking strategic locations" along the border fence, allowing them to drive through in pickup trucks, Spielman said. Civilians in some of the local communities have been ordered to evacuate, while others have left voluntarily, according to Spielman.

"We do have a lot of ground troops in this area. We have a lot of tanks. We have, in addition, artillery. And we're prepared forever for anything," he said. "And if it happens, the next stage, it's going to happen here because this is the area that was the flashpoint and this is the area we're going to be presenting ourselves and finishing this battle. We, of course, have no choice but to finish."

When asked about the mounting casualties of Palestinian civilians in Gaza as a result of the IDF's retaliatory airstrikes, Spielman said: "We always try to avoid civilian casualties. However, I would say that this is war and our first priority here is to destroy Hamas."
