Three tourists from Brazil were killed and more than 20 other people injured after a collision between two hot-air balloons collided in Turkey.

One ascending balloon was torn open as it hit the basket of another, and then plunged to the ground, according to witness reports.

The accident happened yesterday in Cappadocia, a region popular with tourists for its spectacular volcanic rock formations, 190 miles from the Turkish capital of Ankara.

One tourist said the skies were crowded, and about 100 balloons had taken off early on Monday morning, the BBC reported.

The passengers onboard the stricken balloon were mostly tourists from Brazil, Argentina and Spain, according to Abdurrahman Savas, governor of Nevsehir province, who visited the injured in hospital.

He said two Brazilians, aged 65 and 71, had died.

A third Brazilian, aged 76, died in hospital hours later, Turkey’s Anatolia news agency reported.
