Two people have died after two helicopters collided during firefighting efforts near Psatha in the Attica region of Greece, authorities reported on Monday. The incident occurred as aerial crews were combating a large wildfire that has destroyed over 100 homes northwest of Athens.

According to the Hellenic Fire Service, the helicopters involved were both Bell models leased by the fire department, each carrying two crew members. The collision took place during the operation to control the blaze. Video footage shared on social media showed the two helicopters converging at low altitude before the main rotor of the lower helicopter struck the underside of the one above it. The lower helicopter subsequently crashed in flames.

The two fatalities were identified as a Danish pilot and a Greek flight coordinator aboard the aircraft that went down. The second helicopter, operated by a Greek and a British crew member, survived the collision. After the accident, it released its water load and exited the area, with both crew members unharmed.

The fire service confirmed that search-and-rescue operations were underway following the crash. The wildfire itself continues to challenge firefighting teams and has led to the destruction of numerous properties in the region.

In addition to the Attica fire, a new wildfire has emerged on the island of Kefalonia, prompting evacuations due to its threat to local communities and tourism infrastructure.

The Greek authorities remain engaged in extensive efforts to contain the multiple active fires amid hot and dry weather conditions contributing to the fire risk.
