Spain's Defence Ministry has ordered its staff to stop browsing sports and entertainment web sites while on duty, an Associated Press report said.
The newspaper El Mundo said the restrictions stem from recent incidents in which computer systems overloaded and nearly crashed.
The report also quoted a ministry official saying the order distributed this week affects staff at the ministry building as well as the army, navy and air force headquarters. The official spoke on condition of anonymity, in line with ministry rules.
The official said the order did not come directly from Carme Chacon, 37, who took over last week as Spain's first female defence minister, the report said.
