One of the strikes hit a building in Zawayda town in the centre of the enclave and followed a warning by the Israeli army for the owners of the property to leave the area, residents said.
Medics said flying debris and shrapnel that spread for dozens of metres around had wounded at least six people, including the four-year-old, Mohammad Abdel-Salam Taha, who was later pronounced dead at hospital.
"There is no ceasefire, there is nothing," said Abu Ahmed, a displaced Palestinian who was sheltering close to the building, which the air strike reduced to a pile of mangled steel and concrete.
"We want solutions, we want to live in peace," he said.
The second air strike took place in the nearby Nuseirat refugee camp, the health officials said.
Israel's military said it was looking into both strikes.
An October 2025 US-backed ceasefire halted major fighting in the shattered territory but it failed to end strikes by the Israeli military, which it said aimed to thwart attacks by Hamas and other militants.
The military said in a statement late on Saturday that it had struck and killed a senior Hamas militant, Sharif Al-Hasnat, in the city of Deir al-Balah.
It said he was leading efforts to restore Hamas' "underground infrastructure".
Hamas accuses Israel of violating the ceasefire and undermining efforts to implement a broader plan by US President Donald Trump to end the Gaza Strip conflict, which also includes Israeli withdrawals and Hamas disarmament.
More than 1280 Palestinians have been killed in the territory since the ceasefire took effect last October, according to Gazan health officials, while the Israeli military says four Israeli soldiers have been killed.
In the Israeli-occupied West Bank, an Israeli man was stabbed and wounded by a suspect believed to be a Palestinian man, police and the Israeli military said.
Security camera footage distributed by the military showed a man waiting by a vehicle next to a main highway near Jericho before stabbing the Israeli man when he approached his parked car.
The suspect fled on foot and Israeli soldiers were searching for him, the military said.
Elsewhere in the West Bank, health officials said Israeli forces had shot and killed a 14-year-old boy, Islam Ajjouri, during a raid into Askar refugee camp near Nablus.
The Israeli military said it was looking into the incident.
The West Bank, home to three million Palestinians and 500,000 settlers, has had an increase in settler violence and seizures of land and resources.
United Nations bodies and most countries view the settlements as illegal under international law regarding military occupations.
Israel disputes this and it cites biblical and historical ties to the land.
