Western journalists were refused entry to an energy industry conference in Azerbaijan earlier this month, reigniting concerns over the state’s crackdown on the media ahead of crucial UN climate talks in Baku later this year.

At least three journalists from the UK and France have told the Guardian that they felt “unsafe” after they were denied entry to the Baku Energy Week forum, despite registering with the event organisers weeks in advance.

The journalists said they were not given a valid reason why they had been turned away, but they chose to leave the venue after “frightening” and “intimidating” encounters with the organisers.

The journalists left the venue after overhearing an organiser say “take them away” in Russian while on the phone. They said they believed that this was a call to the venue’s security personnel.

“When you’re in a country with no press freedom, where local journalists are jailed, you don’t mess around,” Eales said.
