Russia may have helped Iran rebuild missile arsenal during ceasefire with U.S.

"Iran has most likely replenished its missile stocks with new Russian weapons and restored a significant part of its missile arsenal.
Many Iranian ballistic missiles and launchers were reported to have been "entombed", meaning they were covered by debris that blocked the entrances to the underground storage facilities where they were kept. Tehran most likely used the ceasefire to reopen these depots and move its stockpiles." Pravada
