The funeral procession stopped in several Iranian cities before reaching Tehran on Monday, where a prayer ceremony took place for Soleimani. During his time as head of the Quds force, Soleimani helped spread Iran's influence in Iraq, Syria, Lebanon and Yemen. (Atta Kenare/AFP)

Soleimani's casket was driven through the streets of Tehran, where thousands chanted anti-United States slogans. His burial will take place on Tuesday in his hometown of Kerman. (Atta Kenare/AFP)

Mourners burnt American and Israeli flags. Though Israeli Prime Minister Benjamin Netanyahu has backed Donald Trump's decision to kill Soleimani, Israel is at pains not to be held accountable for the general's death and attract violent repercussions. (Atta Kenare/AFP)
