The U.S. military fired another wave of ship- and submarine-launch missile strikes against Houthi-controlled sites Wednesday, U.S. Central Command said, marking the fourth time in days it has directly targeted the group in Yemen as violence that ignited in the wake of the Israel-Hamas war continues to spill over in the Middle East. The strikes were launched from the Red Sea and hit 14 missiles that the command deemed an “imminent threat.” The strikes followed an official announcement Wednesday that the U.S. has put the Houthis back on its list of specially designated global terrorists. The sanctions that come with the formal designation are meant to sever violent extremist groups from their sources of financing. For in-depth analysis and a deeper perspective on the Houthis' abrupt pivot from peace negotiations to an explosive international conflict, FRANCE 24's Tom Burges Watson is joined by Helen Lackner, Author of "Yemen: Poverty and Conflict", Visiting Fellow at the European Council for Foreign Relations and Research Associate at SOAS.
