Foreign Secretary James Cleverly said:
The execution of Mohammad Mahdi Karami and Seyyed Mohammad Hosseini by the Iranian regime is abhorrent.
The UK is strongly opposed to the death penalty in all circumstances and the Iranian regime has done further lasting damage to its reputation at home and overseas with yet another disproportionate response to the Iranian people protesting legitimately against their oppression.
We have and will continue to make our views clear to the Iranian authorities – Iran must immediately halt all executions and end the violence against its own people.
