The Geneva-based International Committee said Monday that three trucks have crossed the Gaza border.

Hospitals in the Gaza Strip are overwhelmed since the ‘Israeli' warplanes and helicopters launched an ongoing bombardment across the coastal enclave since Saturday.

The attacks have so far left at least 345 people killed and another 1550 others wounded, Palestinian medical sources told Press TV.

"The hospitals are overwhelmed and unable to cope with the scale and type of injuries that keep coming in," Marianne Robyn Whittington, a Red Cross health delegate in Gaza, said in a statement from the organization.

Pierre Wettach, head of the Red Cross' delegation in Palestine, also said it was essential to allow emergency supplies to enter Gaza.
