Hamas said its delegation will travel to Cairo on Saturday to resume Gaza ceasefire talks with a "positive spirit" in the latest effort to halt almost seven months of war with Israel.

Foreign mediators have been waiting for a Hamas response to a proposal to halt the fighting for 40 days and exchange hostages for Palestinian prisoners.

"We emphasise the positive spirit with which the Hamas leadership dealt with the ceasefire proposal it recently received, and we are going to Cairo in the same spirit to reach an agreement," the Palestinian militant group posted on its website on Friday.

"We in Hamas and the Palestinian resistance forces are determined to achieve an agreement that fulfils our people's demands for a complete cessation of the aggression, the withdrawal of the occupation forces, the return of the displaced, relief and reconstruction, and a serious exchange deal," the statement said.
