ADEN, Yemen - The leader of Yemen's Houthi group has warned Israel of significant retaliatory actions if hostilities in Gaza resume.

In a televised address late on Saturday, the first day of Ramadan, Abdul-Malik al-Houthi spoke from Sanaa that renewed Israeli military operations in Gaza would trigger a Houthi military response against Israeli territories, with a special emphasis on targeting Tel Aviv.

"We stand firmly committed through religious, humanitarian, and ethical obligations to support our Palestinian brothers and sisters, along with resistance forces, particularly the Qassam Brigades," al-Houthi said.

Al-Houthi affirmed that the Houthi forces stood ready to open multiple military fronts in solidarity with Gaza if Israel resumes military operations.

The Houthi group, which controls large swathes of northern Yemen, including the capital Sanaa, has previously targeted vessels they say are linked to Israel in the Red Sea, actions it describes as support for Palestinians during the Israel-Hamas conflict.

On Saturday, the 42-day initial phase of the three-stage agreement between Hamas and Israel expired, with no breakthrough announced for the next phase.
