Pakistan's cricket tour of Bangladesh scheduled to start later this week has been postponed, the Bangladesh Cricket Board (BCB) announced on Thursday.
Pakistan was due to reach Dhaka on Saturday to play two Twenty20 matches and five one-day internationals from March 10-22.
The BCB did not say why the tour had been postponed or when it will take place.
'The Bangladesh Cricket Board has postponed Pakistan's tour of Bangladesh 2009 as advised by the Government authorities,' it said in a brief statement.
'A fresh itinerary will be announced later.'
The Pakistan Cricket Board confirmed that tour had been postponed and that the itinerary was being revised.
'Bangladesh have conveyed their decision to us without giving any reason,' PCB official Saleem Altaf, told AFP.
But he added: 'We are told they are revising the tour itinerary and the series will be held after some delay.'
Pakistan was due to arrive in Dhaka on Saturday to play two Twenty20 matches and five one-day internationals from March 10-22.
The PCB did not say why the tour was postponed or when it would take place.
The decision to call off the tour comes two days after the Sri Lankan cricket team was attacked by armed gunmen in Lahore, which injured seven players and the team's assistant coach.
Reports here suggested, however, that the International Cricket Council had sent a new security plan to all member countries with requirements that must be implemented before international matches.
Dhaka was the scene of a bloody mutiny last week from soldiers of the Bangladesh Rifles that left 74 people, including 56 army officers, dead.
