The World Economic Forum recently released their Travel and Tourism Competitiveness Report, which analyzes the travel and tourism sectors in 136 countries.The report includes a ranking of how safe those 136 countries are for tourists.The ranking is based on the prevalence of violence and terrorism, and not on petty crime.The top five most dangerous countries are Nigeria, Pakistan, El Salvador, Yemen, and Colombia. As a part of this report, the WEF ranks the safety of each of those country according to “measures the extent to which a country exposes tourists and businesses to security risks mainly related to serious harm to people (violence and terrorism).” The ranking does not take petty crime into account. We rounded up the 15 most dangerous countries from the report, based on safety and security. .1. Democratic Republic of the Congo:The Congolese armed forces, as well as other armed groups and bandits, are active in many parts of the country, and they are pretty violent. Because the Congolese military is in operation throughout the country, travelers are likely to come across troops, armored vehicles, and attack helicopters. 2.Thailand:The provinces of Yala, Pattani, Narathiwat, and Songkhla – all of which are in southern Thailand – are the most dangerous in the country. In the last 13 years, more than 6,500 deaths have occurred in these areas due to violence. There’s also a martial law in effect in the region. 3.Jamaica:While there are currently no travel advisories for Jamaica, violent crime and shootings are still rampant in some parts of the country, like Kingston and Montego Bay. Even guests staying in resorts can be affected 4. South Africa:High crime rates in South Africa have led many locals to hire private security guards to protect them. Rape and murder occur frequently, especially in the more remote townships and settlements 5.Guatemala:Guatemala’s border with Mexico is one of the most dangerous parts of the country because of frequent drug and alien smuggling. The country also had the fifth highest homicide rate in Latin America and the Caribbean last year. Other common crimes include carjacking, armed robbery, and thef 6.Chad:ISIS, Al-Qa’ida, and Boko Haram are all active in Chad. In the past, attacks by these extremist groups have targeted not only civilians and security forces, but also foreigners. 7.Bangladesh:Besides the threat of terrorist attacks, extreme weather also affects Bangladesh, putting the country at risk for a number of natural disasters. The Asian nation experiences tropical cyclones, flooding, and sometimes earthquakes. . 8.Mali:The risk for terrorist attacks is high in Mali’s capital, Bamako, as well as other parts of northern and central Mali. Hotels and restaurants are often the targets for these attacks; in November of 2015, a number of people were taken hostage and killed at a Radisson Hotel in Bamako 9..Lebanon:Because multiple extremist groups are active in Lebanon, terrorist attack such as bombings happen frequently. It’s also typical for protests and smaller disputes between neighbors or families to escalate and turn violent, causing harm to bystanders. 10.Philippines:In addition to the recent shooting and fire at a Manila Casino, kidnappings are common throughout the Sulu Archipelago and the southern Sulu Sea. Foreigners are often the targets of these kidnappings. .11. Nigeria:Two extremist groups, Boko Haram, and Islamic State West Africa, are responsible for much of the violence that occurs in Nigeria, and commonly target heavily populated areas like churches, schools, restaurants, hotels, and entertainment venues.The U.S. Department of State says visitors “should be vigilant at public gatherings and locations frequented by foreigners,” and to “Exercise extreme caution throughout the country due to the threat of indiscriminate violence.” 12.Yemen:Rebel groups based in Yemen’s capital, Sanaa, continue to both target and detain US citizens. Extremist groups such as Al-Qa’ida are also active in the country, and because of land mines and air strikes, much of Yemen’s population lacks basic necessities like food, water, and medical assistance. 13.Colombia:While Colombia isn’t as dangerous as it once was – Medellin was named South America’s best destination last year – visiting the country still poses quite a risk for foreign travelers. 14 Egypt:ISIS and other extremist groups pose serious threats to public venues throughout Egypt, including tourist sites. The groups have also been known to target various modes of transportation. 15.Kenya:While many terrorist attacks occur outside of Nairobi, the threat of terrorism is still high in the city. Grenades, shootings, and stabbings are common forms of attacks.
