Firefighters gained control over some of the dozens of wildfires scorching Portugal on Wednesday, as fears mounted that weather conditions could further fan the flames.

Three wildfires were raging in Spain's region of Castile and Leon early on Tuesday, the most severe one near Avila, about 100 km (62 miles) west of Madrid. People in the town of Mombeltran were ordered to remain inside due to the smoke.

Hundreds of firefighters are battling wildfires across Portugal as extreme heat and strong winds threaten to worsen the situation. The entire country remains on high alert due to a “maximum or very high” fire risk,
