On Monday, the United States military revealed it has struck more than 800 targets in Yemen since March 15 in operations to dismantle Houthi forces that pose threats to regional stability and international shipping routes.

Pentagon officials released a statement detailing these strikes, noting they were part of an ongoing campaign to “degrade the capabilities” of Iran-backed Houthi movement, which has been accused of carrying out attacks against commercial ships in both Red Sea and Gulf of Aden waters. U.S. Central Command (CENTCOM) indicated these operations targeted missile sites, drone facilities, radar installations, and logistical hubs used by Houthis.

“These strikes are intended to protect freedom of navigation, defend international trade routes, and ensure the security of our forces and allies in the region,” explained General Michael Kurilla of CENTCOM. “We remain dedicated to taking necessary actions that deter hostile activities while limiting civilian casualties.”

Houthis fighters who control much of northern Yemen including its capital Sana’a have strongly denounced U.S. strikes, labelling them acts of aggression and vowing to continue operations against “hostile foreign forces.” Houthi representatives claimed several U.S. attacks hit civilian areas — an accusation denied by Pentagon authorities.

Since the launch of U.S. military operations in March, tensions in the Red Sea region have seen dramatic increase. Shipping companies have reported disruptions and insurance rates for vessels passing through have spiked significantly. According to President Biden’s administration, their military actions are defensive in nature and necessary in protecting international commerce against what it describes as unlawful Houthi aggression.

Human rights groups, however, have expressed alarm at the intensifying conflict. Organizations such as Amnesty International have called for transparency and accountability from all parties involved, encouraging all to comply with international humanitarian law to avoid civilian casualties.

Conflict in Yemen began in 2014 and has already caused one of the worst humanitarian crises ever witnessed worldwide, with millions displaced and dependent on foreign aid. Many analysts warn that increasing U.S. military involvement may further entrench Yemen’s conflict while undermining efforts for an amicable peace settlement.

U.S. officials have expressed concerns over military operations taking place against any group threatening regional security, but have pledged that military operations will go forward regardless. “We will act decisively against any group that threatens international shipping or our partners in the Middle East,” according to Sabrina Singh of Pentagon spokespersons.
