State news agencies TASS and RIA, citing the ministry, said the aircraft lost communication before going down on the Black Sea peninsula, which Russia annexed from Ukraine in 2014.

The ministry said the dead included 23 passengers and six crew members, with no survivors reported.“The An-26 aircraft, with which communication was lost earlier, crashed into a cliff,” TASS quoted officials at the crash site as saying.

Authorities located the wreckage in Crimea, though further operational details were not immediately disclosed.Russia’s defense ministry did not provide additional comment outside regular business hours.

RIA news agency reported that, according to an initial assessment, technical problems were believed to have caused the crash.

No confirmation was given on whether an official investigation had been launched or if other factors were being examined.

The An-26 is a Soviet-era twin-engine turboprop widely used for military transport and logistics operations.

The Igla-S is a man-portable air defence system (MANPADS) that can be fired by an individual or crew to bring down an enemy aircraft.

“We have already signed the corresponding document and now, together with an Indian private company, we are organising the production of Igla-S MANPADS in India,” TASS quoted Alexander Mikheyev, head of the state arms exporter Rosoboronexport, as saying.

India is the world’s largest arms importer and Russia remains its largest supplier despite the damage to the reputation of its army and weaponry from the war in Ukraine, where Russia has suffered numerous setbacks at the hands of a smaller but highly motivated and Western-equipped military.

According to the Stockholm International Peace Research Institute (SIPRI), Russia accounted for 45% of India’s arms imports between 2018 and 2022, with France providing 29% and the United States 11%.

Another Russian state news agency, RIA, quoted Mikheyev earlier as saying that “Rosoboronexport is working with Indian private and public enterprises to organise joint production of aviation weapons and integrate them into the existing aviation fleet in India”.

No details were provided about which Indian companies would be involved or when potential production would start.

Mikheyev said Rosoboronexport and Indian partners had provided the Indian Ministry of Defence with Su-30MKI fighter jets, tanks, armoured vehicles and shells.

At the beginning of the year, India and Russia also started joint production of AK-203 Kalashnikov assault rifles.
