Bangladesh have postponed Pakistan's forthcoming tour of the country following government advice about security concerns.
The decision comes two days after seven people were killed following an armed attack on the Sri Lanka team in Lahore.
The tour was set to begin on 10 March and encompass two Twenty20 matches and five one-day internationals.
The Bangladesh Cricket Board's decision to postpone the tour is yet another setback for Pakistan, who had announced a 16-man squad for the tour on Wednesday.
The Bangladesh capital Dhaka was the scene of a bloody mutiny last week involving the country's border guards that left 74 people dead.
However, PCB chief executive Salim Altaf told BBC Radio 5 Live he is expecting a revised itinerary from the Bangladesh cricket authorities in the near future.
"If beefed-up security measures are to be put into place, and that's going to take a little bit of extra time, the postponement is fine with us," he said.
The PCB is already suffering financial losses following a 14-month hiatus of Test cricket.
Captain Younus Khan, recently appointed to succeed Shoaib Malik for the two-Test Sri Lanka series, has urged the ICC to ensure Pakistan does not become a pariah destination.
Pakistan had been scheduled to hold the Champions Trophy in September 2008, but the tournament was postponed because of security fears.
And the ICC announced in February it was seeking a new host country for the competition, a further setback for the beleaguered PCB.
New Zealand are considering whether to cancel a tour of Pakistan in December.
