KATHMANDU, July 12 (Xinhua) -- The Tribhuvan University Part-time Teachers' Association has called a Kathmandu Valley general strike for Friday to protest the killing of a teacher by an unidentified gang on July 10, local leading media group's website THT Online reported Thursday.

    A meeting of the association on Thursday decided to call a general strike in Kathmandu Valley where capital Kathmandu, Patan and Bhaktapur are located.
