Protesters carry a dead crow as they chant anti-government slogans during demonstrations against the ruling CNDD-FDD party's decision to allow President Pierre Nkurunziza to run for a third five-year term in office, in Bujumbura, Burundi on Thursday. A senior U.S. diplomat told Burundi's President, Pierre Nkurunziza, on Thursday that the east African country risks boiling over if it stifles political opposition, as protests against the president entered a fifth day. Tom Malinowski, U.S. assistant secretary of state for democracy, human rights and labor, arrived in Burundi on Wednesday to try to help halt escalating unrest and defuse the country's biggest crisis in years, set off by Nkurunziza's decision to seek a third term in office
