Iranians gather in the northeastern city of Mashhad on January 5, 2020 to pay homage to slain major general Qasem Soleimani, after he was killed in a US strike in Baghdad. - The air strike was ordered by US President Donald Trump, who said the Iranian general had been planning an "imminent" attack on US diplomats and the roughly 5,200 American troops deployed in Baghdad. Soleimani's assassination ratcheted up tensions between the arch-enemies and sparked fears of a new war in the Middle East. (Photo by MOHAMMAD RAJABIAN / IRAN'S FARS NEWS AGENCY / AFP)
