WARSAW (Reuters) -Poland has no conclusive evidence showing who fired the missile that caused an explosion in a village near the Ukrainian border, the president said on Wednesday, adding that Warsaw remained calm in the face of what he described as a "one-off" incident.

Two people were killed in the explosion in Przewodow, about 6 km (3.5 miles) from the border with Ukraine, firefighters said. Media reports said the strike hit a grain-drying facility.
