A massive crowd has filled the streets of Tehran for the funeral of Ayatollah Ali Khamenei, the late supreme leader of Iran. He was killed at the beginning of the war with the US and Israel. Video from state TV shows many mourners watching Khamenei's coffin, which is covered with a flag. The coffin is being taken by a truck along a 10-kilometer route through famous areas of the capital. His funeral follows two days of public viewings at the Grand Mosalla mosque. Many people show their feelings with flags and signs. Some signs blame the US president for Khamenei's death. People are angry and throw stones at a billboard with his picture. Khamenei's sons attend the funeral but one son does not come. This son is injured and has not been seen recently. The procession marks the end of three days of grieving. Khamenei led Iran for many years and his death is very significant.
