The British Foreign Office has today issued a stark warning for UK nationals visiting Portugal, due to the country being struck by a deadly outbreak of wildfires that has claimed at least three lives.

A state of alert has been announced by Portugal’s government as they seek international help to combat the numerous fires. The Foreign Office advised: “There are currently a significant number of forest fires burning in several parts of Portugal. The Portuguese government has declared a state of alert until 11:59pm on Thursday 19 September. Access to forests and activities in rural areas may be restricted. Roads may be closed due to smoke and ash.”

“The situation is fast-moving and could change rapidly. Keep up-to-date with developments and follow the advice of the Civil Protection Authority.”

In the fight against the infernos, over 5,000 firefighters are on the front lines, while the blaze has been described by the Prime Minister of Portugal as an unruly force “raging across the country”.

A firefighter tragically passed away due to “a sudden illness” while fighting a fire in Oliveira de Azemeis, as Portugal experienced temperatures soaring above 30C (86F) over the weekend, with the heat set to persist throughout the week. Local media have reported at least two fatalities linked to the wildfires.

Portugal is on high alert, with authorities warning of the maximum risk of wildfires igniting across numerous central and northern areas until Wednesday, and the danger level remaining “very high” into Friday.

The fires have already scorched ten thousand hectares (37 sq miles) between Porto and Aveiro in the north, with 128 active wildfires reported as of Tuesday.

Hospitals in the impacted regions are treating individuals for burns, respiratory issues, and other fire-related injuries, according to local news outlets. Police have closed several motorways, including the key route connecting Lisbon and Porto.

At least 12 firefighters have sustained injuries, with two in serious condition. In response to the crisis, the EU is dispatching eight firefighting aircraft to assist Portugal in managing the devastating fires.

EU Commission President Ursula von der Leyen announced that the bloc is “urgently mobilising” support and called on member states to provide additional aid. Portuguese Prime Minister Louis Montenegro expressed gratitude towards France, Greece, Italy, and Spain for their “rapid and essential help in combating this scourge” in a statement on social media.
