On 25 February 2022, the day after the start of the 2022 Russian invasion of Ukraine, ICC Prosecutor Karim Ahmad Khan stated that the ICC could "exercise its jurisdiction and investigate any act of genocide, crime against humanity or war crime committed within Ukraine."[6] Khan stated on 28 February that he intended to launch a full ICC investigation and that he had requested his team to "explore all evidence preservation opportunities". He stated that it would be faster to officially open the investigation if an ICC member state referred the case for investigation,[7] under Article 13(a) of the Rome Statute, rather than under proprio motu of Article 13(c), which would also establish jurisdiction, but would be slower.[7]
