Hundreds of opposition Bangladesh Nationalist Party supporters protested Sunday to mark International Human Rights Day, as the country gears up for a general election on January 7 that the opposition says should be held under a non-partisan, caretaker government.

The party, led by former Prime Minister Khaleda Zia, is boycotting the election, leaving voters in the South Asian nation of 166 million with little choice but to re-elect Prime Minister Sheikh Hasina’s Awami League for a fourth consecutive term.
