Qatar's lead negotiator on the talks, Mohammed al-Khulaifi, says in an interview with CNN: "Our work is not done.

"We're still going to continue to talk more to the parties, to de-escalate, to seek a longer period of ceasefire."

He adds that initially the Israelis were not considering even a temporary pause in fighting "so we remain hopeful".

"Our efforts are not going to stop to this level. We're going to continue working."
