Terrorism has cast a further doubt over Cricket Australia's rescheduled Bangladesh tour.
The trip was delayed and then postponed last September because of security concerns, then rescheduled for either July or September next year.
At the start of this month, terrorists killed 20 foreigners during an attack in Dhaka, the nation's capital.
CA also withdrew the national under-19 team from this year's World Cup in Bangladesh.
Australia were the only Test-playing nation not to field a team in the tournament.

CA chief executive James Sutherland said on Wednesday it was far too early to make a call on whether next year's Test tour should proceed.
"On these sorts of things, I try not to look too far ahead," he said.
"I guess there's a lot of water to go under the bridge."
Sutherland noted other countries would tour Bangladesh before the Australians were due to go there.
England are scheduled to tour this October.
"We're all concerned, obviously, but for us it's not really on the horizon," he said.
"We'll wait and see - obviously, we'll work through our processes.
"There's a whole lot of due diligence you do along the way on a regular basis, but the intensity around that gets a lot greater as you get closer."
Australia last played Tests in Bangladesh in 2006 and their most recent tour there was 2011 for one-dayers.
