A spokesperson for the Israel Defense Forces (IDF) claims the Palestinian terror group Hamas is engaged in an “active effort” to prevent Gaza’s population from evacuating to the southern area of the strip.

“We see an active effort by Hamas to block and prevent the population from going south. Hamas wants to show the world that it has casualties and dead,” IDF spokesman Rear Adm. Daniel Hagari said, the Times of Israel reported.

“We continue to urge the residents of Gaza City, go south… Hamas wants you as human shields… This is for your personal safety,” the spokesperson added, according to the outlet. “We are going to attack very widely in Gaza City in the near future.”

Israel told residents of northern Gaza to move south as the IDF prepares for a possible ground invasion in response to the Hamas-led terror attack that killed 1,300 people and wounded 3,200 more. At least 27 Americans are believed to be dead, CBS News reports. Israel estimates that 150 people are being held hostage in Gaza.

Meanwhile, Israeli Forces have already conducted “localized raids” into Gaza, according to Fox News.

“The IDF tells Fox News that Israeli forces entered the Gaza Strip today, both infantry forces and tanks, to conduct localized raids,” Fox News’s foreign correspondent Trey Yingst first reported on Friday. “This was not the full-scale invasion that everyone is still anticipating, but it was an effort, according to the Israeli military, to eliminate militants along the border and also to gather information on those held hostage inside the Gaza Strip.”

The IDF is said to have deemed the raids successful and is in the process of finalizing plans for a “significant ground operation” in Gaza, which it said will include a “joint and coordinated attack from the air, sea and land.”
