The Daily Star quoting a report published by the Global Sufi Organisation said the attacks involve vandalism, arson, looting, and murder.

The organisation demanded an immediate judicial probe into all attacks.

The group also asked for enhanced security for those religious structures.

The group also wanted authorities to prohibit anti-Sufi sermons at mosques and religious gatherings and compensation for the damaged structures and the families of those affected in the attacks.

Hasan Shah Dipu Noore, a member of the organisation's central executive committee, told The Daily Star that followers of Sufism are peace-loving and are not involved in any criminal activities.

Every person in this country has the freedom to practice their own religion, he said.

"It is a matter of grave concern that followers of the Sufi saints are being attacked," he said.

Bangladesh has been witnessing a spike in attacks on minorities, including Hindus, ever since Hasina's exited the country amid violent protests against her government over a job quota issue.
