The Iran-backed Houthi militias have moved large amounts of their weapons to their main stronghold of Saada in northern Yemen to protect them against US strikes that have intensified on the Amran province in a bid to destroy the militias’ underground arms caches.

Informed Yemeni sources said the Houthis have moved rockets and drones from Amran to Saada in the north, fearing they may be targeted by US strikes.

Western strikes have already destroyed several arms depots.

The US conducted its latest strikes against Houthi positions on Friday, targeting the Harf Sufyan district in northern Amran bordering Saada.

The sources told Asharq Al-Awsat that Houthi “weapons engineers and military maintenance” personnel moved sophisticated rockets and drones and other types of weapons to fortified caches throughout Saada.

The process was carried out in utmost secrecy and in stages to avoid detection, they added.

In Amran, the Houthis carried out a series of kidnappings against the local population, even its own supporters, on suspicion the people were collaborating with the US and Israel.

The US has carried out dozens of attacks on military positions in Harf Sufyan, destroying facilities that have been used to launch attacks against ships in the Red Sea and Gulf of Aden.

Harf Sufyan is considered the Houthis’ second major stronghold after Saada given its large area that spans around 2,700 square kms. It also borders four other provinces: Hajjah, al-Jawf, Saada and Sanaa.

Moreover, sources in Amran told Asharq Al-Awsat that Harf Sufyan is a major recruitment center for the Houthis, including the forced recruitment of Yemenis.

They revealed that the US strikes in the area dealt the Houthis heavy blows because they directly targeted their military positions, including a drone factory.

The sources suspected that the Americans intensified their strikes on Harf Sufyan after receiving intelligence information that the Houthis had dug tunnels and underground facilities there to hold meetings and recruit new members.
