British electronica duo Leftfield announced Friday that they would be cancelling their scheduled performance in Israel on August 31st due what they referred to as production problems.

"Unfortunately Leftfield will not be able to perform at the Heineken Music Conference on the 31st August due to unforeseen production problems," the duo wrote on the Facebook fan page dedicated to their current tour.

Meanwhile, on the duo's official Facebook page they published a letter sent to them by the organization Boycott Israel calling for  them to "postpone your planned concert in Israel this summer, indefinitely."

The letter, scanned and posted on their page, stated that in light of Israel's deadly raid on the Gaza flotilla in May, they urged the musicians to take a stand and protest Israel's actions by cancelling the show.

"Performing in Israel today means crossing an international picket line," the letter said, adding that, "your visit here will be construed as a vote of confidence in Israel's oppressive policies."

In their cancelation statement the group made no reference to the letter, despite the fact that they had made it public by posting it on their Facebook page.

Leftfiled joined a growing list of artists and musicians who have recently cancelled their shows in Israel due to political reasons, among others were Elvis Costello, The Pixies, Jill Scott Heron, Santana, The Klaxons and the Gorillaz Sound System.
