Shelling and gunfire in Gaza City, but no ambulances to help wounded

Middle East Eye contributor Mohammed al-Hajjar is currently in the west of Gaza City, at the heart of heavy fighting. He describes the current situation in the past few moments: 

Clashes renewed in the western section of Gaza City on Tuesday after a brief lull, in the Sheikh Radwan and Nasser neighbourhoods (located around 1km east of al-Shifa hospital).

Very close heavy artillery can be heard by residents trapped in their homes. There's also sounds of explosion from gunshots periodically.

Shelling can be heard targeting apartments in high rise residential buildings. Shrapnel flies everywhere, with some of it entering into people's homes.

Streets are empty and there's no movement. We can only hope no one is wounded because no ambulance vehicles are able to evacuate people.

There's no communication with civil defence workers or anyone else.
