Schools told to keep children inside as polluted fog envelops Bosnian capital

SARAJEVO, Bosnia-Herzegovina (AP) — Flights were cancelled, children were told to stay indoors and outdoors construction work was banned in Sarajevo Thursday as a thick layer of fog enveloped the Bosnian capital. The city is located in a valley surrounded by mountains which can keep polluted air stuck for days at a time if there is no wind. Several flights from Sarajevo airport were cancelled, and cars moved slowly in low visibility during the morning rush hour.
