KABUL (Reuters) - Two Taliban suicide bombers on Thursday killed at least 27 people and wounded around 40 in an attack on buses carrying newly graduated cadets on the western outskirts of Kabul, officials said.

The attacks underline the threat to security in Afghanistan about a week ahead of a NATO summit in Warsaw, where leaders are expected to discuss whether to maintain support for the Kabul government 15 years after the Taliban were driven from power.
