Panic swept through Lagos yesterday as a massive explosion rocked the Dangote Refinery, Africa's largest oil processing plant. The blast, caused by a suspected gas leak, injured five workers, two critically. Eyewitnesses described a scene of chaos with thick black smoke billowing into the sky. Aliko Dangote, Africa's richest man, issued a statement promising a full investigation while emergency services battled to contain the damage. This incident raises serious questions about safety standards at the $20 billion facility, just months after its celebrated launch.
