One more thing to worry about. Brazil gunmen shoot at convoy carrying nuclear fuel in Angra dos Reis.
Gunmen have attacked a convoy of trucks carrying uranium fuel to a nuclear power plant near the Brazilian city of Rio de Janeiro, police say.
The convoy came under attack as it drove past a community controlled by drug traffickers in Angra dos Reis, a tourist city 145km (90 miles) from Rio.
And yes, uranium fuel is 235U.
