The Al-Qassam Brigades, the armed wing of Hamas, officially confirmed on Monday that its longtime spokesperson, widely known by the nom de guerre Abu Obeida, and senior leader Mohammed Sinwar were killed during the ongoing conflict with Israel. In a video statement, the group acknowledged the loss of several high-ranking figures who had led the organization through nearly two years of devastating warfare in the Gaza Strip. This marks the first official confirmation of the death of the masked figure who became the primary face of the group’s media and psychological operations.

Why It Matters

The confirmation of these deaths marks a significant milestone in the dismantling of Hamas’s veteran leadership structure. Abu Obeida was not only a spokesperson but a central pillar of the group’s media strategy, effectively serving as the voice of the resistance for over a decade. Meanwhile, the loss of Mohammed Sinwar—the brother of former leader Yahya Sinwar—indicates that Israel’s targeted operations have reached the highest echelons of the group’s remaining military command.

What to Know

In the Monday statement, the Al-Qassam Brigades revealed the true identity of their spokesperson for the first time, identifying him as Hudhayfah Samir Abdullah al-Kahlout. While the Israeli military had claimed to have killed Abu Obeida as early as August, the group had remained silent until now. The video also confirmed the death of Mohammed Sinwar, who had reportedly succeeded Mohammed Deif as the brigades’ chief of staff following Deif’s assassination.

Beyond the top-tier leadership, the group listed several other fallen commanders, including:

• Mohammed Shabanah: Head of the Rafah Brigade.
• Hakam al-Issa and Raed Saad: Key military leaders within the organization.

These names join a growing list of high-profile casualties that include political chief Ismail Haniyeh, who was killed in Tehran, and Yahya Sinwar, the architect of the October 7 attacks.

What People Are Saying

The new, masked spokesperson for the Al-Qassam Brigades framed the deaths not as a defeat, but as a continuation of the group’s ideological struggle. “We announce with pride the martyrdom of the great leader Abu Obeida,” the successor stated, adding that the movement has “inherited his title” and will continue its operations. The group also used the announcement to name a new spokesman to maintain their communication channels.

Internally, the group remains defiant. Despite the heavy losses among their command staff, the new representative emphasized that the movement would not disarm, stating that they would fight “with our fingernails” if necessary.

What Happens Next

While Hamas leadership has been heavily impacted, the group insists it remains committed to the ceasefire that took effect on October 11. However, they have accused Israel of repeated violations and warned that their right to respond is “guaranteed.”

The humanitarian cost continues to rise as the political situation remains volatile. According to the Palestinian health ministry, the total death toll since October 2023 has surpassed 71,000, with hundreds of casualties reported even after the ceasefire was established. The international community is now facing increased pressure to ensure the current truce holds while the group transitions into a new, and perhaps more decentralized, leadership phase.
