The Islamic State has long targeted leading officials in the Saudi monarchy for their perceived apostacy. The terrorist organization has placed the Kingdom in its sights once again by calling on its supporters to target oil pipelines and other economic infrastructure for attack.

"Targets are plenty ... Start by hitting and destroying oil pipelines, factories and facilities which are the source (of income) of the tyrant government," the spokesman, Abu Hamza al-Muhajir, said in a recorded speech on the militant group's official telegram channel.

The Islamic State was particularly displeased with the Kingdom's recent support for Gulf states' normalization of relations with Israel.

Saudi Arabia, which has Islam's holiest sites and is the world's largest oil exporter, has stressed the need to step up efforts to reach a lasting and sustainable peace agreement among Palestinians and Israelis.
