Igor Grechushkin, the Russian owner of a cargo ship linked to the 2020 Beirut port explosion, has been arrested in Bulgaria. This comes nearly five years after Lebanese authorities issued arrest warrants for him and the ship's captain, Boris Prokoshev. Grechushkin was detained at Sofia airport after arriving from Cyprus, and Lebanese officials are preparing to request his extradition for questioning. The explosion killed 218 people and caused extensive damage, with ongoing investigations facing political challenges.
