Hundreds of thousands of members of South Korea's Christian groups held a service in Seoul on Sunday to protest against a landmark court ruling that acknowledged the rights of partners in same-sex couples to receive state health insurance.

The supreme court in July upheld a high court ruling that a same-sex partner was eligible for spousal benefits from the National Health Insurance Service, a move hailed as a win for LGBTQ rights in a country that has lagged others in the region.

Sunday's massive service drew hundreds of thousands of Christians from across the country, disrupting traffic on several major roads in central Seoul.
