Guinea-Bissau’s Interior Minister Antonio Suka Ntchama became the second minister to step down in the tiny West African country amid an investigation into how 74 Syrians boarded a flight to Portugal with fake passports. Foreign Minister Fernando Delfim da Silva stepped down last Friday after the incident earlier this month stoked tensions with former colonial power Portugal. Portugal’s Foreign Ministry said a “serious breach of security” at Bissau airport had allowed the asylum seekers to board the plane with “proven false documents”. Portuguese carrier TAP has canceled its three weekly flights to Guinea-Bissau until there is a complete re-evaluation of security conditions.
