The terrorist attack on the mausoleum is an obvious violation of international law, the statement said, adding that all those involved must be brought to justice.
The council noted that international human rights organizations and those Western states that claim to support the principle of human rights have demonstrated complete disregard and lack of reaction to terrorist acts when it comes to Iran.
On Wednesday, Iranian media said three unidentified persons opened fire in the grounds of the Shah Cheragh mausoleum in south Iran.
Iranian media reported that there was only one shooter, while the Iranian state broadcaster said that there was also a second attacker who was not far from the mausoleum.
As a result of the attack, at least 13 people were killed and another 45 people were injured. The Iranian authorities accused the US and Israel of organizing this terrorist act to further fuel instability in the country amid mass unrest over death of female activist.
