By 3 PM, the Pentagon reported that 50 Tomahawk missiles had been fired, joined by 40 bomber and fighter aircraft that targeted sites around several Afghan cities. The targets were essentially strategic sites, chosen to cripple the Taliban's airpower.
Many US allies, including Israel, defended the United States actions. British Prime Minister Tony Blair told his nation that the Taliban had been “given the choice of siding with justice or siding with terror, and they chose to side with terror.”
The Taliban called the US action a "terrorist" act. My personal opinion is that, due to language differences, the Taliban may not be clear on the meaning of terrorism. Terrorism is usually defined as attacking non-combatants without warning and is different than striking military targets after weeks of warning. They may, however, learn.
