Assault on Pakistani Ambassador

Today Mohammad Bakhsh Abbasi, Pakistani ambassador to Iran, got assaulted by an Afghan in northern Tehran. Abbasi just got slightly wounded on his head and his hands but already seems to be in a good condition again. Official sources say the aggressor got caught by Iranian police shortly after the incident had happened. So far the motive of the assault remains unclear. The Associated Press wrote that the Afghan attacked the ambassador after both had argued with each other. But it is still unclear wether they were arguing about politics or something else.
