Portugal has declared a day of national mourning to mark the deaths of seven who died in wildfires that have burned through the country's west coast.

Portugal has brought under control the remaining forest fires it battled this week in the north of the country, rescuers said on Friday.

More than 100 wildfires are stretching thousands of firefighters to the limit in northern Portugal. The country’s worst spate of fires in recent years is blamed for seven deaths since they spread out of control over the weekend.
