The Interior Ministry says Spain remains on high alert as firefighters combat wildfires in hot, tinder-dry conditions across the southern half of the country, according to AP. Ministry officials say at least 24,000 hectares (59,304 acres) have been charred by fires that have killed six people in just over a week. Seven active fires were still being fought late Sunday. Some of the fiercest outbreaks, in Aragon and Catalonia, were close to being extinguished. Officials believe at least one fire was caused by lightning, one was started accidentally by a tourist in Andalusia, and one in western Caceres may have been started deliberately and is being investigated. An outbreak in Lesaka in northern Navarra was under control the ministry said in a statement.
