Talks between mediators and Hamas leaders in Cairo on implementing a US-brokered peace plan for the Gaza Strip have made rare progress, sources close to the effort say although an Israeli official says proposed terms are not satisfactory. Earlier, Israeli strikes killed at least six Palestinians in the Gaza Strip on Thursday, including two children, medics said. A Hamas official and a diplomat close to the Egyptian talks said discussions were “positive” and “making progress”. However, the Israeli official, who declined to be identified, said Israel had rejected a proposal. Hamas wants Israel to commit to ending attacks on the Gaza Strip and withdrawing its forces.
