Mark Regev, chief spokesman of the Israeli Prime Minister told ITV News the airstrikes that killed four children yesterday were a "terrible mistake" and an "operational failure".
Mr Regev said he did not think any Israeli officer would deliberately target children, and that there were legitimate targets nearby.
Speaking to ITV News Presenter Alastair Stewart he said it was still unclear whether a ceasefire could be agreed or held by Hamas, if the past ceasefire brokered by Egypt was anything to go by.
It's been an emotionally exhausting day in Israel and Gaza as hopes for peace were raised then dashed then raised then dashed again.
In the court of international opinion, this is how Israel wins a battle and still manages to lose the war.
Until the Israelis and the Palestinians find a way of resolving the underlining conflict this will not be more than a pause.
