Here is the info from their web site:
"We are sorry to inform you that the planned shows in Tel Aviv and Haifa have been postponed. After having conversations with the Norwegian
Foreign Department (UD) the APB Management decided to postpone
the shows in Israel. The Norwegian Foreign Department does not advice
Norwegians to visit Israel at the moment, but we will come back
with new dates for these shows as soon as possible.
The APB Management would like to state that this is not a political
decision but strictly a matter of APBs security.
