The country has underlined its unwavering commitment to closely monitoring the situation and taking incidents of violence seriously, as per Dhaka Tribune.

During a routine briefing held at the US Department of State on Tuesday, spokesperson Matthew Miller stressed Washington's active engagement with various stakeholders in Bangladesh, including the government, opposition and civil society, saying the primary objective of these engagements was to encourage collaboration among these groups for the benefit of the Bangladeshi people and to ensure a free and fair election conducted in a peaceful manner.

"We do believe that dialogue is important to achieving those goals," he said.

Miller said holding free and fair elections is the responsibility of everyone - all political parties, voters, government, civil society and the media.

"And what we want in Bangladesh is the same thing the Bangladeshi people want, which are free and fair elections conducted in a peaceful manner," the US State Department spokesperson said.
