USA Issues Travel Warnings to Its Citizens in Nigeria

The United States of America has issued a travel warning to its citizens travelling to Nigeria or living in Nigeria and names 20 states to avoid.
Their statement reads;Security measures in Nigeria remain heightened due to threats posed by extremist groups, and U.S. citizens may encounter police and military checkpoints, additional security, and possible road blocks throughout the country. All U.S. citizens should remain aware of current situations including curfews, travel restrictions, and states of emergency in the areas they are in or plan to visit.
"Kidnappings remain a security concern throughout the country. Criminal elements throughout Nigeria orchestrate kidnappings for ransom; Islamic extremists, operating predominantly in the North, also have been known to conduct kidnappings. Criminals or militants have abducted foreign nationals, including U.S. citizens, from off-shore and land-based oil facilities, residential compounds, airports, and public roadways.
"Militant groups have destroyed oil production infrastructure in Bayelsa and Delta states.  U.S. citizens are advised to avoid the areas of these states where these incidents have occurred. Attacks by pirates off the coast of Nigeria in the Gulf of Guinea have increased substantially in recent years.  Armed gangs have boarded both commercial and private vessels to rob travelers. The Nigerian Navy has limited
capacity to respond to criminal acts at sea."
The states to be avoided include; Bauchi,Yobe,Bornu,Adamawa, Bayelsa, Delta, Edo, Gombe, Imo, Jigawa, Kaduna, Kano, Katsina, Kebbi, Kogi, Niger, Plateau, Rivers, Sokoto, and Zamfara.
