Singapore's Pink Dot LGBT rights rally will allow only Singaporean citizens and permanent residents to attend this year's event because of legal changes.
Organisers announced the restrictions with "profound regret", saying they had been reminded of new rules by police in the wealthy city state.
Previously only locals were allowed to actively "demonstrate" by holding up placards, but foreigners could nonetheless attend, Pink Dot says.
The Pink Dot rally has been held annually since 2009 in the country's Speakers' Corner, where demonstrations are allowed without a police permit. About 30% of Singapore's population are neither citizens nor permanent residents.
