Israel's devastating war against Gaza has killed 8,005 Palestinians, including 3,324 children, the besieged enclave's health ministry has said.
Communications were restored to many people in Gaza early on Sunday, according to local telecoms companies, internet-access advocacy group NetBlocks and confirmation on the ground.
Bombardment had knocked out most communications in the besieged enclave late on Friday, largely cutting off the territory's 2.3 million people from the world.
Israeli warplanes carried out airstrikes early on Sunday near Gaza's largest hospital, which is packed with patients and tens of thousands of Palestinians seeking shelter, residents said.
Residents said the latest airstrikes destroyed most of the roads leading to al-Shifa Hospital in Gaza City, in the northern part of the besieged territory.
Tens of thousands are sheltering in al-Shifa, which is also packed with patients wounded in the strikes.
"Reaching the hospital has become increasingly difficult," Mahmoud al-Sawah, who is sheltering there, said over the phone. "It seems they want to cut off the area."
Israel has claimed Hamas has a command post under the hospital, without providing much evidence. The armed group has denied the allegation.
The Israeli military had no immediate comment when asked about reports of strikes near al-Shifa.
In a sign of growing chaos in Gaza, the UN's agency for Palestinian refugees, UNRWA, said thousands of people broke into its Gaza aid warehouses to take food and other "basic survival items" like hygiene products.
Thomas White, the agency's director in Gaza, said the break-in was "a worrying sign that civil order is starting to break down".
UNRWA, provides basic services to hundreds of thousands of people in Gaza. Its schools across the territory have been transformed into packed shelters housing Palestinians displaced by the conflict.
