Gaza crisis: Hamas upbeat on ceasefire hopes
A senior representative of Hamas has said that some "tough points have been solved" in negotiations with Israel and that a ceasefire could be declared within hours.
Osama Hamdan was speaking as talks between Palestinian and Israeli negotiators continued in Beirut.
Israel launched its offensive, which it says is aimed at ending rocket fire from Gaza, with the killing of a Hamas military leader on Wednesday.
More than 110 Palestinians and three Israelis have been killed since then.
