The Pakistan and Bangladesh cricket boards have agreed to postpone April's planned Test and ODI encounters amid the coronavirus pandemic.
Bangladesh, who visited Pakistan for Test and Twenty20 matches earlier this year, were due to arrive back in the country on March 29 to complete the final leg of their three-part, multi-format tour.
Those plans are now on hold, with the two boards set to discuss options for rescheduling the second Test that was due to begin in Karachi on April 5.
A standalone ODI had also been scheduled to go ahead in Karachi on April 1.
A Pakistan Cricket Board (PCB) statement read: "The Pakistan and Bangladesh cricket boards have decided to postpone the upcoming One-Day International and Test in Karachi for a later date.
"The two boards will now work together to identify a future opportunity to complete the ICC World Test Championship commitment."
Pakistan beat the Tigers by an innings and 44 runs in the first Test in Rawalpindi in February.
The unusual fixture arrangements emerged as a compromise after the Bangladesh Cricket Board expressed concerns over security and player safety in Pakistan.
Meanwhile, the PCB has also indefinitely postponed the domestic one-day Pakistan Cup tournament, which was scheduled to start on March 25.
