New Delhi, May 21 Bangladesh pacer Nahid Rana and two key members of the coaching staff have withdrawn from the upcoming T20I tour of Pakistan, citing security concerns, just days before the team's scheduled departure.

The Bangladesh Cricket Board (BCB) confirmed that fielding coach James Pamment and strength and conditioning coach Nathan Keily will also not travel with the squad, as the team prepares for a three-match series in Lahore on May 28, 30 and 31.

Rana's withdrawal comes in the aftermath of a tense episode during the Pakistan Super League (PSL), when he, along with several overseas players including Rishad Hossain, had to urgently exit the country following escalating border tensions between India and Pakistan.

Rana was part of the Peshawar Zalmi squad when the incident occurred earlier this month, and his experience appears to have left a lasting impact.

"You can't blame them for being traumatised," said BCB cricket operations chairman Nazmul Abedeen Fahim. "What Nahid Rana and Rishad faced recently was a difficult situation. While Rishad has chosen to go on this tour, Rana decided to pull out, and that's completely understandable."

Fahim acknowledged that a few other players were initially hesitant about touring but decided to travel once reassured by the presence of the majority of the squad.

"Pakistan provides the highest level of security for touring teams. I witnessed this during the Champions Trophy and have no doubts about their commitment. PCB chairman Mohsin Naqvi personally assured us of the best possible protection."

Originally slated to be a five-match series, the Pakistan-Bangladesh T20I contest has now been trimmed to three games, with all fixtures to be played at Lahore's Gaddafi Stadium.
