United States sanctions have impacted League of Legends users in both Iran and Syria.

That's according to the game's forums - as spotted by Dot Esports - which has seen users from these regions complaining that they are unable to access Riot's MOBA.

"Due to US laws and regulations, players in your country cannot access League of Legends at this time," a message reads when League of Legends is booted up.

"Such restrictions are subject to change by the US government, so if and when that happens, we will look forward to having you back on the rift."

This isn't an extraordinary incident; both EA's Origin client and the Epic Games Store are blocked in these regions.

Riot is yet to put out a statement on the matter. We'll update this story as more details emerge.
