from the above article:
"We have suspended our operations in Gaza until the Israeli authorities can guarantee our safety and security," said Chris Gunness, spokesman for the United Nations relief agency Unwra.
"Our installations have been hit, our workers have been killed in spite of the fact that the Israeli authorities have the co-ordinates of our facilities and that all our movements are co-ordinated with the Israeli army.
"It is with great regret that Unwra has been forced to make this difficult decision."
Earlier, Unwra said one person had been killed and two injured when a fork-lift truck on a UN aid mission came under Israeli tank fire at Gaza's Erez crossing.
More than 700 Palestinian and 11 Israeli lives are said to have been lost since the offensive began 13 days ago.
While the BBC has had Palestinian producers reporting from Gaza, Israel only allowed Western TV crews to enter on Wednesday, embedded with its army.
