It began as Khan allegedly shared a number of inaccurate news items on Twitter, including old videos and clippings, during the past few week.
The oddity was pointed out by some netizens, but it caught the spotlight after Iqrar posted an elaborate video, highlighting the flaws in Khan's posts.
Iqrar is said to have quoted at least 15 tweets posted on Khan's Twitter handle, to substantiate his point.
According to Iqrar, if the journalist realised his sharing of non-factual information at some point in time, he should have tendered an apology.
But the video invited a swift rebuke from the journalist. Without naming him, Khan announced to block him on the social media platform.
Before doing so, the journalist called the Sar-e-Aam presenter a mental patient. "My friends had advised me to avoid him completely,” he said and added, “they were right.”

In the same tweet, he admitting to having a liking for Iqrar’s work in the past, but lamented, “That effort stands wasted.”
Both Khan and Iqrar have a massive fan following, and so netizens advised them to avoid a confrontation.
They also said that the TV presenter did criticise Khan but he did not resort to the use of foul or abusive language, something which is commonplace nowadays.
Some Twitter users thought that it would have been wise for Khan to not block Iqrar to keep a possibility of reconciliation alive.
Many saw the online brawl as a reason for the fans of both the personalities to themselves engage in a fight.
The political divisions in the country have pushed many to engage in abusive, insulting, and defamatory campaigns against each other.
