Over 100 people were injured and approximately 20 to 30 shops were looted during an attack by unidentified assailants in the Habiganj district of northeastern Bangladesh, United News of Bangladesh reported on Saturday.

The attack, which occurred on Friday afternoon and left two individuals in critical condition, may have been triggered by the appointment of a new imam at a local mosque, according to the report.

It added that in response to the unrest, authorities deployed the army, border guards, and police forces to bring the situation under control.

The situation has since stabilized, and an investigation is underway, the report mentioned.

Bangladesh's turmoil

Bangladesh has been witnessing turmoil since student-led protests demanding the resignation of Prime Minister Sheikh Hasina erupted.

Hasina, 76, fled to neighboring India by helicopter last week after thousands of protesters stormed her official residence, ending her 15 years of rule.

More than 450 people were killed in the weeks of protests leading up to her August 5 ouster, most by police fire.

The ousted premier accused the United States of orchestrating her overthrow after she refused to give up sovereignty over the key island of St. Martin.

Days after, Nobel Peace Prize winner Muhammad Yunus was sworn into office to lead Bangladesh's interim government as its chief advisor.
