Area of concern
The three key developments shaping maritime security, with new threats emerging across strategic waterways from the Gulf of Aden to the Arabian Sea.
Gulf of Aden: Houthis sustain missile threats despite international strikes
On 29 September 2025, the Dutch-flagged MV Minervagracht was struck by an anti-ship cruise missile while transiting the Gulf of Aden — the latest in a series of Houthi attacks targeting commercial shipping. The strike is believed to have involved a Mandab-2 missile launched from Al Bayda Province in Yemen, a system derived from Iranian and Chinese designs and part of a growing Houthi arsenal supplied via complex smuggling networks.
Despite U.S. and Israeli airstrikes targeting Houthi missile infrastructure and supply routes throughout 2025, including key operations at Ras Isa and Hodeidah, the group has maintained the capability to threaten the Maritime Security Transit Corridor.
