In the two separate terms and 20 years that she has been the Prime Minister of Bangladesh, the ongoing protests that have seen over 300 people killed, is perhaps Sheikh Hasina's biggest test. At least 98 people were killed and hundreds injured in Bangladesh on Sunday as police used tear gas and rubber bullets to disperse tens of thousands demanding the resignation of PM Hasina. The violence marked one of the deadliest days in Bangladesh's recent history of civil unrest, surpassing the 67 deaths reported on July 19 when students protested against the quota system for government jobs.
