Bomb parts seized by security forces in Saudi Arabia and Bahrain match explosives supplied by Iran to Houthi militias in Yemen, a new report reveals.

The electrical components for improvised explosive devices (IED) were also identical to those seized from a ship off the coast of Yemen in 2013, according to Conflict Armament Research (CAR), an organization that tracks smuggled weapons.

The cargo vessel was laden with missiles, rockets and ammunition when it was intercepted by US and Yemeni forces after leaving Iranian waters. UN experts said the regime in Tehran was behind the shipment.

The link raises concerns that Iran-backed militant groups have tried to spread bomb-making expertise into eastern Saudi Arabia from cells in Bahrain, CAR said.

“There is some evidence to suggest that the increasing domestic capacity of militant factions to manufacture homemade explosives — and IED more broadly — may extend from Bahrain to nearby regions of Saudi Arabia,” it said.

CAR researchers studied IED parts captured from militant groups between 2013 and 2018 in Bahrain, where security forces have been targeted by insurgents.

They also recorded details from components seized in a raid in Awamiyah in eastern Saudi Arabia in April 2017, where militants clashed with security forces for several months.

Another seizure also took place on a bus on the King Fahd causeway that links Bahrain and Saudi Arabia

Components from the seizures, including infrared sensors, and radio-controls “are identical or similar” to components documented in Yemen after their capture from Houthi forces and to those found on the cargo ship in 2013, the report said.

“The components either originated in Iran or are linked to Iranian-backed supply networks in the region.”

Iran supports and supplies the Houthis with weapons and has been accused of supporting militant Shiite cells in Bahrain. Arab countries blame Tehran for destabilizing the Middle East with its support of proxy forces, including Hezbollah in Lebanon and armed factions in Iraq.

In Bahrain, the level of sophistication for IED increased dramatically after 2013, when security forces started to intercept ships carrying readymade bomb components among supplies of conventional weapons. The bombs have killed at least 14 security force members and injured dozens in Bahrain since 2013. Before that, crude devices had been used amid protests and rioting in 2011.

The report found that the militants stored the explosive and non-explosive components at separate locations and delayed assembly until close to the time of use.

This “implies that militant factions use relatively sophisticated tactics, techniques, and procedures” and “centralize the construction of non-explosive components in preparation for onward distribution.”

Researchers also found information that usually helps identify components, such as circuit boards, had been systematically removed. The only other place they had seen this carried out to such an extent was in Yemen, among components seized from the Houthis.

“It’s striking that those involved in the supply chain chose to obliterate identifying information and serial numbers of RCIED circuit boards, at a rate much higher than found in CAR’s data set from investigations in Iraq and Syria,” CAR executive director James Bevan said. “It indicates a concerted effort among parties to the illicit supply chain to conceal the origins of materiel and prevent investigations like ours from tracing supply routes.”
