The head of Lebanese Shiite movement Hezbollah on Tuesday called for “resistance,” a day after the United States recognized Israeli sovereignty over the Golan Heights, AFP reported.

In a televised speech on Tuesday, Hezbollah chief Hassan Nasrallah said the only option left to Syrians to take back their land—and for Palestinians to achieve their “legitimate rights”—was “resistance, resistance, and resistance.”

He described US President Donald Trump’s move as “a crucial turning point in the history of the Arab-Israeli conflict.”

Trump’s decision “deals a knockout punch to what is called the peace process in the region,” Nasrallah added, in particular.

Donald Trump on Monday formally recognized Israel’s sovereignty over the Golan Heights and signed a respective order.
