Gilad Sharon, son of former Israeli Prime Minister Ariel Sharon, said on Sunday that entire neighbourhoods in Gaza ought to be flattened.
The BBC has a special report on the conflict - the latest analyses pieces are to be found there.
Israel's Haaretz newspaper quotes the Israel Defense Forces as saying 40 smuggling tunnels between Gaza and Rafah were bombed overnight. Gaza stadium used for launching rockets also attacked. It says 95 Palestinians have been killed since the beginning of the operation.
The BBC's Middle East editor Jeremy Bowen says these situations always end up with a ceasefire - but, as an Israeli official put it, "it may need to get worse before it gets better". But both sides are making demands that are not practical.
