It was a Friday of mourning for the nation as flag-draped coffins of 11 soldiers were brought to the capital Ankara for a state ceremony. President Recep Tayyip Erdoğan, families and dignitaries gathered at a mosque to pay tribute for "martyrs," including a general, whose lives cut short with a helicopter crash.

The Eighth Corps Commander Lt. Gen. Osman Erbaş and his entourage were traveling from the eastern province of Bingöl to the Tatvan district in Bitlis on Thursday afternoon. About half an hour later, communications were cut off with their helicopter. In the evening, authorities announced it crashed in a rural area in Tatvan. Only two soldiers aboard survived the incident. An investigation is underway, but initial findings show bad weather in the region including thick snow and occasional blizzards were to blame.

All of the victims were career military officers, from specialist sergeants to the lieutenant general. Erbaş was traveling to Tatvan for a routine inspection of a military force deployed there, according to reports.

Speaking to reporters after a military funeral for soldiers in the eastern province of Elazığ, the minister of national defense said initial information and eyewitness accounts show the accident was caused by suddenly changing adverse weather. Teams of investigators were deployed at the snow-covered crash site on Friday for further investigation. This was the fourth crash involving Cougar-type helicopters which were first acquired by the army in 1996.

After the funeral in Elazığ, the soldiers' bodies were taken to Ankara for a "state ceremony." Funeral prayers were performed at Ahmet Hamdi Akseki Mosque in the capital, with the participation of Erdoğan, ministers, politicians, families of victims and a huge crowd of citizens. The soldiers will be buried in their hometowns later.

"Martyrdom is the most honorable form of death. May Allah bestow it upon us as well," President Recep Tayyip Erdoğan said in remarks following the funeral. The president delivered a eulogy for Osman Erbaş at the funeral. "Our commander was known for his modesty, his humble stance. He was a different person. With this tragic accident, he and my other brothers gave back what Allah gave them. I hope we will meet again (in the afterlife)," Erdoğan said.
