"Thousands of mourners gathered at Hussaini Dalan in Old Dhaka on Monday to mourn the death of Iran's Supreme Leader Ayatollah Ali Khamenei. The organisers described the massive turnout as a show of religious solidarity. Footage shows members of Bangladesh's Shia community joined by Sunni supporters marching through the streets with flags of Iran and portraits of Khamenei, and chanted slogans. "Iran has been attacked from American bases in the Middle East. By establishing bases in the region, America has turned all Muslim countries into its vassal states, leaving them powerless to advocate for Muslims and against the US. We urge the OIC (Organisation of Islamic Cooperation) to reconsider its purpose," said one of the protesters. "We call on the Bangladesh government to vehemently protest and resist the attack on Iran. Stop supporting the UN and the US, and stand firm for Muslims," added another. Ayatollah Ali Khamenei was killed in joint US-Israeli strikes carried out against Iran on Saturday, Iranian state television confirmed. The Supreme Leader, who had ruled since 1989, held ultimate authority over Iran's political, military and religious institutions.  Iranian officials warned that Khamenei's killing would mark a turning point, with the Revolutionary Guard vowing retaliation and declaring that "this great crime will not go unpunished."  Washington and Tel Aviv launched coordinated strikes on 'Iranian military targets' on Saturday, with US President Donald Trump and Israeli Prime Minister Benjamin Netanyahu stating their intention to dismantle Iran's missile capabilities.  In response, Iran's Islamic Revolutionary Guard Corps announced 'widespread missile and drone attacks' targeting Israel. Reports indicated that US military bases in the United Arab Emirates, Bahrain, Qatar, Iraq, and Kuwait were also targeted.  The escalations follow three recent rounds of nuclear talks between Iranian and American officials, one held in Muscat and two in Geneva."
