Palestinian resistance group Hamas leader Khalil al-Hayya has dismissed the possibility of meaningful change emerging from Israel's upcoming general election, warning that Israeli politicians are campaigning off the "blood" and suffering of Palestinians in Gaza.

"Whether this or that person comes to power, or this party or another - our people have suffered at the hands of all Israeli parties," Hayya told Qatari broadcaster Al-Araby.

"We absolutely refuse to allow the blood, suffering, and cause of the Palestinian people to serve as fuel for Israeli elections. What matters to us is that our people achieve their goals, aspirations and legitimate rights."

Israeli Prime Minister Benjamin Netanyahu faces a tight race to retain power in the October 27, vote, where his main challenger is former military chief Gadi Eisenkot.

Netanyahu has vowed not to withdraw troops from Gaza, rejecting a US-backed peace proposal.

The election is the first since October 7, 2023.

Israel's genocide in Gaza has displaced nearly the entire population of Gaza, destroyed the majority of buildings and killed over 74,000 people.

Palestinian unity and regional diplomacy

Turning to internal politics, Hayya addressed the Palestinian legislative election scheduled for November 28 — the first in two decades.

President Mahmoud Abbas has ruled by decree since Hamas won the 2006 vote.

"We are ready to sit down with President Abbas to lay the foundations for a national programme and achieve genuine unity," Hayya said, noting that if voting is postponed, it must still serve to put "the Palestinian house in order."

Hamas has pursued an alliance with former Fatah figure Mohammed Dahlan to establish a unified front.

However, participation remains uncertain after Abbas required candidates to recognise the Palestine Liberation Organisation's platform.

Regionally, Hayya confirmed Hamas offered to mediate between Saudi Arabia and Yemen's Houthis following escalating attacks on the kingdom.

"I hope that this will be accepted," he said.
