According to media reports, the Israeli armed forces sent call notifications to thousands of reserve personnel before deciding whether to expand the attack on the Gaza Strip.
YNET Israeli news website reported that a major offensive could begin in the coming days.
Israeli security cabinet will discuss the expansion of the Gaza war on Sunday. According to Israeli media reports, Prime Minister Benjamin Netanyahu has agreed in principle to such a plan.
The current Gaza war was triggered by an unprecedented Israeli attack led by Hamas, with about 1,200 people killed and more than 250 people kidnapped to the coastal areas on October 7, 2023.
According to Israel, 35 of the 59 hostages still in Gaza are no longer alive.
Israel is seeking to increase attacks on Palestinian extremist group Hamas to free the rest of the hostages.
The Israeli military resumed the attack on the Gaza Strip on March 18 after a ceasefire that lasted for nearly two months.
The Jerusalem Post reported that the planned mobilization was large-scale, but was still much smaller than the immediate after the Hamas attack in October 2023.
Init said some reserve personnel will replace conventional forces currently deployed on the northern border or the West Bank so that they can be sent to the Gaza Strip again.
The expansion of the attack is likely to further exacerbate the desperate situation in the Gaza Strip, with conditions described by aid organizations as disastrous. Israel blocked aid supplies from entering a sealed area of about 2 million Palestinians, which lasted for two months.
