Akhtar had criticised the Indian players after the drubbing at the hands of England in the semifinal.
Akhtar criticised the selection calls made by both captains, Babar Azam and Rohit Sharma.
Sehwag added that New Zealand pace bowler Shane Bond, who is currently the Mumbai Indians bowling coach, was the toughest fast bowler he faced.
The 'Rawalpindi Express' has also asked the International Cricket Council to remove restrictions on the number of bouncers that can be bowled.
Akhtar posted the update on his Twitter handle.
"A lot of apologies guys, a lot of apologies," Akhtar said before storming off the set.
Former fast bowler Shoaib Akhtar said that New Zealand 'killed Pakistan cricket'.
The Rawalpindi Express had threatened Uthappa during the 2007 One-Day International series.
The 'Rawalpindi Express' also said that India owes Dhoni a grand farewell.
Akhtar said that it was the first time he had done so on purpose and he apologised to the former Indian captain after that.
