Thousands of Israeli protesters have taken to the streets in 20 cities across the occupied lands to condemn the extremist cabinet of Netanyahu as threat to global peace.

Huge crowds marched through Tel Aviv's central street on Saturday, carrying signs that described the regime's new extremist cabinet as a "threat to world peace," and condemning Prime Minister Benjamin Netanyahu's policies.

They also rejected Netanyahu's so-called judicial reforms, which allow the regime's parliament to overrule any Supreme Court decision with a simple majority of 61 lawmakers in the 120-seat body. They will also change the system through which judges are appointed, giving politicians more control.

The rallies have been raging after Netanyahu, who had already served the regime more than any other prime minister, made a comeback as premier at the head of the cabinet that features hard-right and ultra-Orthodox parties.

The protests have now become a weekly fixture on Saturday evenings since Netanyahu's new cabinet, which has been dubbed the most right-wing in the regime's history, took office in late December.

Israel's former prime minister, Yair Lapid, was also among the crowd in the coastal city of Haifa.
