PARIS: Iranian authorities have arrested Toomaj Salehi, a prominent rapper who is sharply critical of the Islamic republic’s leadership, the artist’s supporters said on his social media accounts on Thursday. The reported arrest of Salehi, who is known to fans as Toomaj and had previously been sentenced to death in the wake of nationwide protests, comes amid the nearly week-old war triggered by Israeli attacks on Iran and as rights groups have warned of a crackdown on dissent by Tehran.
