South Africa was rocked by another night of terror as gunmen launched a brutal midnight ambush at a tavern near Johannesburg. Witnesses described vehicles pulling up before armed attackers opened fire without warning, turning a crowded drinking spot into a killing zone. Victims were shot inside the tavern and in nearby streets as people tried to flee. Police say the attack was unprovoked and involved heavy weapons, triggering fears after a similar massacre last month. A massive manhunt is now underway as the nation reels from renewed violence.
