Gaza City sign reads: 'Cemetery is full'
Updated on 13 January 2009
After 18 days of fighting, Israeli soldiers reach Tel Hawwa, the closest they have come to the centre of Gaza City.
There have also been air strikes on Rafah in the south, and shelling in Beit Lahiyah.
The cemetery is full, reads a sign in Gaza City, as Israeli aircraft attacked some 60 targets across the territory.
The head of the Red Cross accompanied an aid convoy into Gaza during a three-hour ceasefire, although witnesses said the shelling continued.
Hamas also kept up its attacks, firing 10 rockets into Israel.
Thirteen Israelis and more than 900 Palestinians have been killed since the conflict began.
