Schools for millions of students in Nepal were closed on Friday as tens of thousands of teachers protested in the capital against an education reform bill in parliament.

Teachers have been demonstrating in Kathmandu since Wednesday against the School Education Bill while teachers’ groups negotiate with government leaders over changes to the legislation.

The teachers oppose provisions that would shift government-run schools to local control, saying it would lower their status, and that would scrap many temporary teacher positions. They blocked the main street leading from the parliament to key government ministries, disrupting traffic in the heart of the capital.
