The Israeli military has said that Hamas militants have carried out "multiple attacks" against Israeli forces beyond the "yellow line" buffer zone, including a rocket-propelled grenade and sniper fire, calling it a "blatant violation" of the ceasefire.
Hamas official Izzat al Risheq said the group is committed to the ceasefire agreement.
It comes amid Israeli media reports that the Israeli military launched an attack on Gaza today.
There was no immediate comment from the military or Hamas on the reported attack.
Israeli public broadcaster Kan said the air force was attacking Rafah in the south of Gaza. Most media outlets described the attack as air strikes.
The Israeli military said on Friday that "several terrorists" opened fire on soldiers in the Rafah area, causing no injuries.
The military later said it struck another group of "terrorists" that were approaching troops in Khan Younis on the same day.
It said the military would continue to operate to remove immediate threats.
The Israeli government and Hamas have been accusing each other of violations of the ceasefire for days, with Israel saying the Rafah border crossing between Gaza and Egypt will remain closed until further notice.
Israel and Hamas have engaged in a row over the return of the bodies of deceased hostages.
Israel demanded that Hamas fulfill its obligations in turning over the remaining bodies of all 28 hostages.
Hamas has returned all 20 live hostages and 12 of the deceased but said the process needs effort and special equipment to recover corpses buried under rubble.
Israel identifies latest returned body as former Thai hostage
Meanwhile, Israel has confirmed that the second of two bodies returned overnight by Hamas was that of a Thai farm worker killed during the 7 October 2023 attack whose body was taken to Gaza.
The prime minister's office said the military had informed the family of the deceased hostage, Sonthaya Oakkharasri, that their loved one had been returned to Israel and formally identified.
