(KABUL, Afghanistan) — A Taliban assault on two adjacent checkpoints in northern Afghanistan killed at least 30 soldiers and policemen, officials said, as life gradually returned to normal on Wednesday in parts of the eastern city of Ghazni after a massive, days-long insurgent attack, with sporadic gunbattles still underway in some neighborhoods. In Kabul, a suicide bomber targeted a training class for university students in a private building in a Shiite neighborhood on Wednesday afternoon, killing one person and wounding 12, officials said.
