DHAKA, Bangladesh (AP) — Bangladesh’s prime minister resigned and fled the country Monday, after weeks of protests against a quota system for government jobs descended into violence and grew into a broader challenge to her 15-year rule. Thousands of demonstrators stormed her official residence and other buildings associated with her party and family.

Prime Minister Sheikh Hasina’s departure threatens to create even more instability in the nation on India’s border already dealing with a series of crises, from high unemployment and corruption to climate change. Amid security concerns, the capital’s main airport suspended operations.

After the embattled leader was seen on TV boarding a military helicopter with her sister, the country’s military chief, Gen. Waker-uz-Zaman, sought to reassure a jittery nation that order would be restored. He said he met with opposition politicians and civil society leaders and would seek the president’s guidance on forming an interim government.
