The Swedish Volvo Trucks company owns 26.5% of Merkavim, an Israeli company which manufactures buses. Merkavim proudly declares on its website that the Israel Prison Authority is in the process of replacing all of its prisoner transportation fleet with buses manufactured by Merkavim. The buses of the Israeli Prison Authority are not only used to transport Palestinian political prisoners from the occupied territory to prisons inside Israel, these buses are also used as mobile interrogation rooms for political prisoners. At the end of this process, interrogation of Palestinian political prisoners by the Israeli General Security Services (the Shabak) will have been conducted in Volvo buses manufactured by a Volvo subsidiary. This marks an increase in the involvement in the occupation of Volvo Trucks, which had already authorized auto-repair shops in West Bank settlements and whose heavy machinery vehicles have regularly been used in the demolition of Palestinian homes, as well as, in the construction of Israeli military checkpoints in the West Bank.
