The Azerbaijan Airlines plane that crashed in Kazakhstan this week suffered physical "external interference", the airline and Azerbaijan's transport minister said Friday, citing preliminary results of an investigation, adding to speculation it was hit by a Russian air defence system.
The jet crashed near the Kazakh city of Aktau on Wednesday, killing 38 of the 67 people on board, after attempting to land at its destination in the Russian city of Grozny and then diverting far off course across the Caspian Sea.
Russia's aviation chief said Friday that Grozny was being attacked by Ukrainian drones at the time the plane had tried to land, but the Kremlin has declined to comment on reports that Russian air defence missiles accidentally shot the plane down.
Statements from Azerbaijan citing the investigation into the incident suggest Baku believes the plane was hit mid-air.
"Based on the opinion of experts and on the words of eyewitnesses, it can be concluded that there was external interference," Azerbaijani's transport minister, Rashad Nabiyev, told reporters.
"It is necessary to find out from what kind of weapon," he added, citing reports from survivors of hearing "three explosions" as the plane was over Grozny.
Azerbaijan Airlines said it had suspended flights to 10 Russian airports, saying preliminary results suggested the crash of Baku-Grozny flight J2-8243 was "due to physical and technical external interference".
The head of Russia's civil aviation agency, Dmitry Yadrov, said in an earlier statement that "the situation on this day and at these hours in the area of Grozny airport was very complex".
"Ukrainian attack drones at this time were making terrorist attacks on civilian infrastructure in the cities of Grozny and Vladikavkaz," Yadrov said, referring to a nearby city.
He said the Azeri pilot made "two attempts to land the plane in Grozny that were unsuccessful" in "thick fog".
"The pilot was offered other airports. He took the decision to go to Aktau airport," he added.
'Explosion'
The Kremlin earlier Friday declined to comment on the deadly crash.
"Until the conclusions of the investigation, we do not consider we have the right to make any comments and we will not do so," Kremlin spokesman Dmitry Peskov told reporters.
Some aviation and military experts have pointed to signs of shrapnel damage on the plane wreckage as evidence that air defence systems hit it.
An Azerbaijan pro-government website, Caliber, and several other media have cited unnamed Azerbaijani officials as saying they believed a Russian missile fired from a Pantsir-S1 air defence system caused the crash.
Ukraine's military intelligence has also claimed this, and Ukraine's presidency said Russia "must be held responsible for the downing" of the plane.
A Russian survivor, Subkhonkul Rakhimov, told state broadcaster RT that an "explosion" appeared to happen outside the plane as it attempted to land in Grozny in fog, causing shrapnel to penetrate inside.
"I wouldn't say it was inside the plane because the skin of the fuselage near where I was sitting flew off," he said.
"I grabbed a life jacket and saw there was a hole in it, it was pierced by shrapnel."
Apology urged
Azerbaijan's President Ilham Aliyev said Friday that he had phoned his Kazakh counterpart Kassym-Jomart Tokayev, with both pledging that the "causes of the crash would be fully examined", according to a statement from Baku.
Contacted by AFP, Azerbaijani government officials did not respond to questions about the possible causes of the crash.
But Rasim Musabekov, an Azerbaijani lawmaker and member of the parliament's international relations committee, urged Russia to apologise for the incident.
"They have to accept this, punish those to blame, promise that such a thing will not happen again, express regrets and readiness to pay compensation," Musabekov told AFP.
He suggested the plane was not allowed to land at Grozny or a nearby Russian airport, instead being "sent far away" across the Caspian Sea to Kazakhstan in an attempt to "cover up a crime."
