Hamas wants a comprehensive deal to end the war in Gaza and swap all Israeli hostages for Palestinians jailed in Israel, a senior official from the Palestinian militant group said, rejecting Israel's offer of an interim truce.

In a televised speech, Khalil Al-Hayya, the group's Gaza chief who leads its negotiating team, said the group would no longer agree to interim deals, adopting a position that Israel is unlikely to accept and potentially further delaying an end to the devastating attacks that restarted in recent weeks.

Instead, Hayya said Hamas was ready to immediately engage in "comprehensive package negotiations" to release all remaining hostages in its custody in return for an end to the Gaza war, the release of Palestinians jailed by Israel, and the reconstruction of Gaza.
