US Secretary of State Marco Rubio has said he expects protests in Iran to flare up again, as people’s main concern – the economy – shows no signs of improving.

“That regime is probably weaker than it has ever been and the core problem they face – unlike the protests you saw in the past on some other topics – is that they don’t have a way to address the core complaints of the protesters, which is that their economy is in collapse,” Rubio said while addressing the Senate Foreign Relations Committee.
