Supreme Leader Ayatollah Ali Khamenei and several high ranked officials was killed in coordinated airstrikes on Iran by the United States and Israel military, according to Daily Post.

These officials includes Abdolrahim Mousavi, Aziz Nasirzadeh, Mohammad Pakpour, and Ali Shamkhani who were reportedly killed during a defence council meeting.

The military operation also claimed the lives of Khamenei’s daughter, grandchild, daughter-in-law, and son-in-law.

Reports from state broadcaster IRIB on Sunday morning declared, "The Supreme Leader of Iran Has Reached Martyrdom," a sentiment echoed by Mehr, a state-affiliated news outlet, which praised Khamenei as "this great scholar and mujahid (fighter) sacrificed his life to lift Iran… and he is in the grand presence of martyrs above."

Iran has announced 40 days of national mourning and declared seven days of public holiday following the death of its Supreme Leader, Ayatollah Ali Khamenei.

The declaration was broadcast on state television on Sunday after Iranian authorities formally confirmed his death.

The United States and Israel had launched the missile strikes, with Israel describing the operation as "pre-emptive" to "remove threats against the State of Israel."

Israeli Defence Minister Israel Katz announced a "special and permanent state of emergency" across the country, cautioning about potential Iranian retaliation with drones and ballistic missiles.

US President Donald Trump publicly confirmed Khamenei’s death on Truth Social, branding him "one of the most evil people in History" and asserting that his death was "Justice for the people of Iran, but for all Great Americans, and those people from many Countries throughout the World."

Trump also stated his pursuit of regime change in Iran, urging the "Iranian people to take back their country."

In response to the attack, Iran reportedly retaliated with drone strikes across several Gulf countries.

Airports and shopping arcades in Dubai were affected, and the UAE, Bahrain, Qatar, and Kuwait closed their airspace on Saturday as Iran targeted US civilian and military assets in the Middle East.

Globally, reactions varied. In Kano, Nigeria, thousands of Muslims converged on the Fagge Jumaat Mosque on Sunday for a peaceful protest, condemning the killings.

Dressed mostly in black, they cried, waved Iranian flags, and held photos of Khamenei, protesting the ongoing US-Israeli attack.

Imam Umar Kurna, an organizer, extolled Khamenei's virtues, describing him as "an honorable leader who died honorably" and "a protector and promoter of the cause of the vulnerable."

A special prayer session was held, seeking divine intervention in the conflict.

Kaduna-based Islamic scholar Ahmad Gumi also reacted, describing Ayatollah Ali Khamenei as a "lucky soul who died in Jihad" against "killers of innocent children and women in Gaza and elsewhere."

In a Facebook post, Gumi asserted that Khamenei’s blood "will fuel the change in the ummah" and praised him for standing "firmly for justice and didn’t hide in bunkers."
