Primary school teachers in Bangladesh joined public sector workers in protests against the interim government on Monday amid growing discontent and political uncertainty in the South Asian country.

Nobel peace laureate Muhammad Yunus, 84, took over as interim head of the country of 173 million last August after deadly student-led protests forced then Prime Minister Sheikh Hasina to flee to India.

Yunus' administration has faced pressure from civil servants, teachers, political parties and the military as the caretaker government attempts to guide the country through a fragile transition before holding a general election.
