Seventy-six people were killed in a collision between a bus carrying Afghan migrants just deported by Iran and two other vehicles in western Afghanistan, a provincial official said Wednesday.

A bus crash in northwestern Afghanistan has killed at least 79 people, including 19 children. Most victims were Afghans returning from Iran.

Nearly 80 Afghans and scores of children died in a fiery bust crash on its way out of Iran to Afghanistan in Iran's ongoing push to rid millions of foreigners.
