The United States and Israel are continuing their strikes against Iran, as Iranian President Masoud Pezeshkian has vowed to avenge the killing of Supreme Leader Ayatollah Ali Khamenei.
Iran has begun 40 days of mourning after Khamenei was killed in the U.S.-Israel airstrikes on Saturday.
On Sunday, explosions were heard near central Tehran, with large plumes of smoke seen rising from several buildings, and fighter jets were also heard hovering overhead, according to a China Media Group (CMG) crew reporting from the Iranian capital.
The U.S. and Israel has launched their coordinated airstrikes against targets across Iran since Saturday, resulting in heavy causalities, many of them innocent civilians.
Iranian state media on Sunday confirmed the killing of Khamenei during Saturday's attacks.
According to the reports, Khamenei was killed when attending a meeting of the country's defense council. Also killed were chief of staff of the Iranian armed forces, chief commander of the Islamic Revolutionary Guard Corps, secretary of the defense council, and the defense minister.
In response, Iran has also continued its counterattacks against both U.S. and Israeli targets, including launching a number of drone strikes and six rounds of missile attacks so far.
Iranian President Pezeshkian released a statement on Sunday, describing Supreme Leader Khamenei's killing a major challenge against the Muslim world by the U.S. and Israel.
Iran considers that it is its duty and legitimate right to hold the perpetrators and masterminds behind Khamenei's death accountable, and will take necessary measures in response, said Pezeshkian, who also called on all Iranians in the country to stay united.
On the streets of Tehran, no traffic congestions were seen during morning rush hours on Sunday, and a local grocery store was well-stocked with daily essentials.
