At least 42 Palestinians including 10 children were killed in airstrikes by Israeli forces on Sunday in Gaza.
Medical personnel in the area confirmed to journalists on Sunday night.
However, the Israeli military has defended its action, saying the act was unintentional as jets attacked a tunnel system used by militants, which collapsed and brought down the homes.
Hamas, the militant group that controls Gaza, called the airstrikes “pre-meditated killing.”
The Israeli Prime Minister, Benjamin Netanyahu, who had earlier met with members of the United Nations Security Council, said his country’s campaign in Gaza was continuing at “full force.”
He added that the destruction of a 12-storey building housing the Associated Press and the Al Jazeera TV network was necessary since it allegedly accommodated a militant group’s intelligence office.
“We are acting now, (and) for as long as necessary, to restore calm and quiet to you, Israel’s citizens. It will take time,” Netanyahu said in a televised address after meeting with his security cabinet on Sunday.
The Palestinian Health Ministry said the death toll in Gaza had increased to 192, including 58 children amid an intensive Israeli air and artillery barrage since the fighting erupted last Monday.
