Houthi rebels in Yemen fired a ballistic missile into Saudi Arabia. The missile was believed to be a Burqan-2, a variant of the Scud. It was launched from Yemen, traveling approximately 600 miles and landing in Riyadh, the Saudi capital. Part of the missile, possibly the warhead, hit near a runway at King Khalid International Airport. The Saudi government claims that it shot down the missile with the U.S.-supplied Patriot missile defense system, although the evidence suggests that the interceptors failed to stop the missile. Iran is suspected of supplying the Houthis with the Burqan-2, a charge which Tehran denies.

Saudi Arabian defense forces intercepted a ballistic missile launched by Iranian-backed Houthi rebels in Yemen on November 4. It was identified by rebels as the Burkan-2H. This missile (and another launched from Yemen in July 2017) has a range of 900 km and was made in Iran, according to Saudi Arabia. Photographs of one of the recovered missiles shows the same markings as those seen on Iran's Qiam missile, according to a report by the Saudi-led coalition. Separately, Saudi Foreign Minister Adel al-Jubeir claimed that the missile intercepted on November 4 had a guidance system and aluminum originating in Iran. 

A spokesman for the Atomic Energy Organization of Iran (AEOI), Behrouz Kamalvandi, said the agency is developing nuclear propulsion for marine transportation using the budget allocated to the AEOI following the U.S. government’s passage of the Iran Sanctions Act. Kamalvandi underscored the project’s complexity, noting that research and simulation would take four to five years to complete. Kamalvandi also claimed that Iran would begin to develop its uranium mines on a much larger scale starting in 2018.

A report by the National Council of Resistance of Iran (NCRI) alleges that Iran’s nuclear weapons program remains active. The report claims that the country’s civilian nuclear program is providing cover for military aspects of the program. The NCRI identifies four military sites involved in nuclear weapon work, including: Pazhouheshkadeh, located at the Parchin military complex; the Nouri Industrial site, located at the Khojir military complex and run by the Hemmat Industries Group; the Hafte Tir site near Isfahan, which is run by IRGC Brigadier General Mohsen Fakhrizadeh-Mahabadi and has been used to produce centrifuge components; and the Sanjarian site east of Tehran. The NCRI claims several of these sites have tunnels and silos that would allow for nuclear work to be transferred. The report asserts that North Korea cooperated with Iran in building the tunnels at the Nouri site, as well as in designing warheads. The report is entitled "Iran’s Nuclear Core: Uninspected Military Sites."
