Pakistan seamer Mohammad Amir has retired from international cricket, the Pakistan Cricket Board confirmed on Thursday. 

The 28-year-old initially announced his retirement from Test cricket in July 2019, citing a desire to focus on limited-overs matches.

However, he has now called time on his international career altogether. 

The Pakistan Cricket Board (PCB) did not provide a reason for Amir's decision, but the bowler said earlier on Thursday that Pakistan management had left him feeling "mentally tortured".

"I am not going away from cricket but I am being pushed away from it," he told Samaa TV.

"The environment that has been created, I feel that I cannot play cricket under this management.

"I feel that I am leaving cricket at this time because I am being mentally tortured."

A statement from the PCB read: "PCB chief executive Wasim Khan spoke with Mohammad Amir this afternoon following reports that the fast bowler had announced his retirement from international cricket. 

"The 28-year-old confirmed to the PCB chief executive that he has no desires or intentions of playing international cricket and, as such, he should not be considered for future international matches.

"This is a personal decision of Mohammad Amir, which the PCB respects, and as such, will not make any further comment on this matter at this stage."

Amir was handed a five-year ban and jailed in 2011 for his part in a spot-fixing scandal after bowling deliberate no-balls against England, returning to international action against New Zealand in January 2016.

Amir claimed 119 wickets and scored 751 runs in his Test career, taking 6-44 in his best bowling innings against West Indies in 2017.
