The statement on its website read: “The Swedish Institute apologises to those who have been blocked mistakenly.”
It explained in the past it had given “its moderators permission to block users, but last week it happened on a larger scale
“The blocks contributed to increased security on the account and to a significant improvement in dialog.
“But the institute also sees the need to examine the question of freedom of expression of authority in this context.”
Mr Bachman had used the social media platform to criticise Sweden’s policies on Israel.
Protesting on Twitter about the fact he had been blocked he wrote: “Now, that #Israel’s MFA and ambassador are blocked — #Sweden is much safer in reading Iran and others [Tweets] that were not blocked @SweInstitute.”
