Palestinian resistance groups are claiming to have killed several Israeli soldiers, taken two prisoners and destroying many armored vehicles, but Israel is only admitting one fatality and many causalities.
"I can confirm that an IDF soldier was killed this morning by a mortar shell in the area of Beit Lahiya," an Israeli army spokeswoman told Agence France-Presse (AFP).
The death, first reported by Al-Jazeera, is the first fatality confirmed by Israel since it launched a ground operation on Saturday.
The Israeli army said another soldier was critically wounded Sunday morning in clashes with Palestinian resistance fighters.
Israel admitted earlier that 30 soldiers have been injured in Gaza fighting, two of whom are in serious condition.
"We believe several Israeli soldiers were killed and dozens were wounded since the ground aggression began last night," Abu Ubaida, spokesman for Ezzeddin Al-Qassam, the military wing of Hamas, told Reuters.
A Hamas statement earlier said two Israeli soldiers were taken prisoners.
"I can neither confirm nor deny that at this stage?" Abu Ubaida said.
He confirmed that Hamas fighters have targeted Israeli tanks and armored vehicles.
