A Legoland theme park in the U.K. was supposed to host a "Muslim family fun day" for 1,000 Muslim families this weekend, but has cancelled the event because right wing extremists made threats.

The Muslim Research and Development Foundation had scheduled the private event at Legoland, but the Windsor, England amusement park received abusive and threatening messages on its Facebook page, noted The Guardian.

According to AFP, before the Muslim fun day was cancelled, a member of the right-wing British National Party said Legoland should be "ashamed of themselves for bowing to these Muslims."

"The Legoland Windsor resort has had to close the hotel on Saturday 8 and Sunday 9 March 2014 after threats from right-wing groups," a Legoland spokeswoman said in a statement. "The safety and security of our guests and our members of staff has to be our number one priority, which is why we've made the difficult decision to close the hotel."

The right-wing English Defence League applauded the decision on its website:

"We are pleased to hear that Legoland Windsor Resort has listened to the complaints of the EDL, its members and concerned members of the public and decided to cancel this event," the website reads.

In response to the cancellation, the Muslim Research and Development Foundation posted on its website:

"Together with these threats, publication of several articles in the national press helped fuel further hatred and resentment towards the event, resulting in further negative impact on the security of the event," the response reads. "It was evident from these hate articles and threats that this was not an attack on MRDF alone but was an outright attack on Islam and Muslims in the UK."
