Iran's semi-official ISNA news agency is reporting the country's Foreign Ministry has summoned Saudi Arabia's top envoy in Tehran over the execution of three Iranian nationals for drug trafficking by Saudi Authorities.

The Sunday report says the Saudi Interior Ministry reported Sunday that three Iranian men were found guilty of drug smuggling and were executed in the eastern city of Dammam.

Iran and Saudi Arabia are at odds over multiple conflicts across the region including in Syria, Iraq, Yemen and Bahrain, underscoring the deep divide between the two regional powerhouses.
