Pakistan captain Younus Khan inspects the bullet-ridden Sri Lankan bus
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.
Pakistan are also set to protest against Chris Broad's criticism of security measures in the country.
Broad - officiating as match referee in the second Test at the Gaddafi Stadium - was in a van with other officials behind the Sri Lanka bus when they came under fire from the masked gunmen.
"I am extremely angry that we were promised high-level security and in our hour of need that security vanished," the former England opener said on Wednesday.
But Pakistan Cricket Board chairman Ijaz Butt refuted Broad's allegations and said he will lodge a complaint with the International Cricket Council, the world governing body.
"All he has said is totally untrue and fabricated," said Butt. "It's unfortunate that a gentleman of such a stature is saying such a thing."
The future will not be good if cricket is taken away from my country
Pakistan captain Younus Khan
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.
"It is up to the ICC and the bosses from around the world to make sure that cricket is not lost in Pakistan because of a couple of mad people," Younus told Cricinfo.
"They must think about all the factors, including what will become of the youngsters of Pakistan. It would be very easy right now for the ICC and the bosses to say there will be no cricket in Pakistan.
"But the future will not be good if cricket is taken away from my country."
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.
