Iran’s Revolutionary Guard Corps (IRGC) have said that it would unveil new targets and weapons, drawing attention to major undersea internet cables crossing the Strait of Hormuz amid tensions with the United States.

Illegal Israeli settler attacks risk setting off an "explosion" in the occupied West Bank, a senior Palestinian leader said, while urging that the response remain peaceful.

"The terrorism carried out by the army and settlers, under the supervision of the Israeli government... is a prelude to a coming reaction and explosion," Rajoub told AFP in Cairo.

But he said that a "peaceful, nonviolent struggle is a necessity and a strategic choice for all Palestinians". "Bloodshed is no longer an acceptable option," he said, calling for "peaceful confrontation with the occupation, despite the crimes it commits".

Government agencies in the Saudi capital have also told employees to work from home starting Monday, one worker and two consultants told AFP, as has the 99-storey Kingdom Centre skyscraper in downtown Riyadh housing the regional office of the International Monetary Fund.
