Global risk and disruption dominated the day’s developments. Reports say Iran has told Yemen’s Houthis to be ready to shut the Bab el-Mandeb strait if Washington strikes Iranian power infrastructure, raising the prospect of a serious shock to shipping and energy markets along one of the world’s most strategic maritime chokepoints. In the Pacific, New Zealand briefly went on tsunami alert after a strong earthquake near Te Anau on the South Island, with residents urged to move to higher ground before officials later lifted the warning as updated assessments reduced the threat. In Nigeria, presidential chief of staff Femi Gbajabiamila has launched a high-stakes N15 billion defamation suit over bribery allegations he rejects as false. And in the United States, new immigration rules will impose fixed admission periods on student, exchange, and foreign media visas, signaling tighter federal oversight of temporary entrants.
