A volcano has erupted near Iceland’s capital Reykjavik, spewing lava and smoke onto the side of a mountain.
The eruption came from a fissure in the ground on the side of Fagradalsfjall mountain, which last year saw an eruption that lasted six months.
The Reykjanes Peninsula is a volcanic and seismic hot spot, and the outbreak took place just 25km (15 miles) from Reykjavik and 15km from the nation’s international airport.
Tourists and residents were told to avoid the area due to poisonous gases, although there was no immediate risk of damage to critical infrastructure, the Department of Civil Protection and Emergency Management said in a statement.
A "code red" was declared to stop planes from flying over the site, although helicopters were sent in to survey the situation, th Icelandic Meteorological Office (IMO) told Reuters.
If the outbreak was confirmed to be similar to the fissures seen last year, the aviation alert would likely be lowered to orange, signalling less danger, an agency spokesperson said.
"Currently, there have been no disruptions to flights to and from Iceland and international flight corridors remain open," the country's foreign ministry said in a statement.
In March last year, lava fountains erupted in the area from a fissure 500 to 750 metres (1,640 to 2,460 feet) long, continuing until September and attracting thousands of Icelanders and tourists to the scene.
Unlike the eruption in 2010 of the ice-covered Eyjafjallajokull volcano, which halted some 100,000 flights and forced hundreds of Icelanders from their homes, this eruption is not expected to spew much ash or smoke into the atmosphere.
Located between the Eurasian and the North American tectonic plates, among the largest on the planet, Iceland frequently experiences earthquakes and has high volcanic activity as the two plates move in opposite directions.
