Police in Bangladesh's capital Dhaka used tear gas and sound grenades on Friday to disperse hundreds of members of the banned militant group Hizb-ut-Tahrir seeking to march to demand the country's secular democracy be replaced by an Islamic caliphate.

Chaos unfolded in Dhaka as a banned Islamist group held a rally after Friday prayers, leading to violent clashes with the police. Protesters took to the streets, defying restrictions, while security forces attempted to disperse the crowds.
