Amidst the outrage around the world for Saudi Arabia executing top Shiite cleric Sheikh Nimr al-Nimr along with 46 other prisoners, the furious Iranians petrol bombed the Saudi embassy in Tehran during their protest.
Nimr was branded a terrorist by Saudi Arabia and convicted of 'terrorism', reports Tolo News.
The Iranian Police later arrested several protestors.
The cleric's execution has drawn widespread criticism.
United Nations Secretary-General General Ban Ki- Moon, who was 'deeply dismayed' by the execution, has asked regional leaders to pull up their socks to avoid the
exacerbation of sectarian tensions.
