French water-bombing planes sent to help Sweden fight a major forest fire have been hampered by too much smoke, according to reports on Wednesday.
"We're doing everything we can to get them in the air as soon as possible," NIklas Ekstrand from the Swedish Armed Forces told the Aftonbladet newspaper.
"The situation is far from perfect right now with so much smoke in the air. Right now, they can't take off with such poor visibility."
The planes, flown in from France on Tuesday, have been called in to help quell the flames as they are able to carry much more water than the helicopters Sweden has been using. Sweden owns no water bombing planes itself.
French planes are regularly sent abroad to help battle forest fires. In August 2012 two were sent to Portugal as forest fires raged across the country.
Two more planes are expected to touch down from Italy later on Wednesday.
Those who have already evacuated the town, however, are not permitted to return until emergency services give the signal.
Evacuated residents of the town of Gammelby, west of the fire, are now able to return to their homes, on the condition that they are prepared to evacuate again at a moment's notice and do not bring their animals back with them.
The blaze claimed one Swedish man's life early on Tuesday morning.
