Iceland has raised an aviation alert for a region close to the subglacial Bardarbunga volcano after a small eruption in the area.
The small fissure took place in the Holuhraun lava field, about three miles north of the vast Dyngjujoekull glacier.
Iceland’s meteorological agency described the eruptionas a “very calm lava eruption and can hardly be seen on seismometers”.
The Civil Protection Department said all airports remained open.
The eruption on Sunday morning is the third to be registered in the area since August 23.
A similar fissure on Friday also prompted flights to be restricted in the area amid a warning to airlines by Icelandic authorities to be vigilant.
