in Tanzania due to crime, terrorism, health, unrest, arbitrary enforcement of laws, and targeting gay and lesbian individuals. Some areas have increased risk. Read the entire Travel Advisory.

Crime

Violent crime happens in Tanzania. It includes assault, sexual assault, robberies, mugging, and express kidnapping.  Crime can happen at any time. It is more common in crowded urban areas and when people are not paying attention. Local law enforcement may be slow to help if a crime happens. 

Terrorism 

There is a risk of terrorist violence, including terrorist attacks and other activity in Tanzania. Visit the U.S. Department of State's country reports on terrorism to learn more. 

Unrest

Demonstrations can take place in response to political or economic issues. The Tanzanian government increases security presence around protests.  This includes checkpoints and roadblocks. The Tanzanian government may limit or prohibit rallies or demonstrations.

The government may shut down or limit internet, cell data, and phone service before, during, or after unrest. The Tanzanian government has used internet laws to punish people who share information perceived as criticizing the government.   

Health 

Medical services for routine and emergency procedures are limited, especially outside of the urban areas of Dar es Salaam and Arusha. Read the Health section of the Travel Guidance on this page for more information.

Arbitrary enforcement of local laws

The Tanzanian government arbitrarily enforces its own laws and regulations. U.S. citizens have been detained or prevented from leaving the country for several weeks without criminal charges. The U.S. embassy cannot guarantee your release.  Local authorities do not consistently report detentions of U.S. citizens to the U.S. embassy in a timely manner. 

Targeting of gay and lesbian individuals  

Same-sex relationships are illegal in Tanzania and carry severe penalties.  Members of the gay and lesbian community have been arrested and harassed. Police may target people who identify as gay or lesbian.

Terrorism

There is risk of terrorist violence, including terrorist attacks and other activity in Saudi Arabia. Visit the U.S. Department of State’s country reports on terrorism to learn more.

Terrorism is a concern in Saudi Arabia. Attacks can occur with little or no warning, especially around holidays. They can involve knives, firearms, and vehicles.

Terrorists may use violence to respond to direct attacks against them or other military operations in the region.

Potential targets include:

• Important political, cultural, or religious sites
• Places visited by U.S. citizens and other foreigners
• Tourist locations and large gatherings
• Hotels and locations where U.S. citizens gather
• Transportation hubs
• Markets and shopping malls

Missile and drone attacks from Iran and threats from Houthis in Yemen

Iran and Iran-backed Houthi rebels have launched missile and drone attacks into Saudi Arabia.

• Attacks have targeted cities, infrastructure, airports, military bases, diplomatic, and energy facilities throughout the country.
• Iran-backed Houthi rebels have threatened to attack Saudi Arabia again.
• Falling debris from intercepted drones and missiles are also a risk.
• U.S. citizens living and working near energy infrastructure and military bases may be at increased risk, especially closer to the border with Yemen.
• Do not photograph, film, or share information about missile or drone interceptions or impact sites. Saudi authorities have detained U.S. citizens for taking photos of recent events.

Exit bans

The Government of Saudi Arabia has imposed exit bans on some U.S. citizens that prevent them from leaving. These can last many years.   

• Exit bans may be related to pending criminal and civil investigations and cases, including, but not limited to unpaid visa overstay fees, domestic family disputes, and other financial and labor disagreements.
• In some cases, exit bans can continue even after a criminal sentence has been fully served or a private suit is settled.

Arbitrary Enforcement of Local laws

• You are subject to Saudi Arabia’s local laws when traveling in the country. The U.S. government cannot guarantee your release if you are detained or arrested abroad.
• If you break laws in Saudi Arabia – even by mistake – you could be deported, fined, imprisoned, or subject to an exit ban.
• Some U.S. citizens have been detained for several months or even years without charges.
• Saudi authorities may detain you if they consider your social media posts or other online activity to be critical, offensive, or disruptive to the public order.
• Some U.S. citizens have been arrested for past social media activity, including comments posted while outside of Saudi Arabia. This may include posting, re-posting, or liking comments critical of the Saudi government or its leaders and policies. This also may apply to comments about public

in Yemen due to risk of terrorism, unrest, crime, health risks, kidnapping, and landmines.

Do not travel to Yemen for any reason, including the island of Socotra. The U.S. Embassy in Sana’a suspended its operations in February 2015. The U.S. government cannot offer emergency services to U.S. citizens in Yemen due to the safety risks.

Unrest

A civil war continues in Yemen. Yemen faces instability and the Houthis have repeatedly clashed with Yemeni government forces. The Houthis have launched missile and drone attacks against Yemeni government personnel, as well as civilians and infrastructure across the country since July 2026. The Houthis have also targeted infrastructure in Saudi Arabia and shipping in the Red Sea and the Bab al-Mandeb.

• Do not rely on significant assistance from local authorities.
• Foreigners are frequently targets of kidnapping and carjacking, especially outside of urban areas.
• Have a plan to leave in an emergency that does not depend on U.S. government help. Review our information on Crisis and Evacuations.
• Military conflict has destroyed basic infrastructure like housing, medical facilities, schools, and utilities. This makes it hard to get electricity, clean water, and medical care. Humanitarian groups face obstacles in delivering food, medicine, and water.

Crime

Violent and organized crime is common in Yemen. Local law enforcement may not be able or willing to respond to serious crimes.

Health

Medical services for routine and emergency procedures in Yemen are limited and poor. There is a re-emergence of diseases like cholera, polio, and measles which are spreading in Houthi-controlled areas. Medicine and medical supplies are hard to find. Adequate medical treatment for routine and emergency procedures is often not available. If you decide to travel to Yemen:

• Read the Health section of the Travel Guidance on this page for more information.
• Visit the CDC’s Travel Health page for the latest information.

Kidnapping

U.S. citizens, especially dual U.S.-Yemeni citizens, are at high risk of kidnapping and detention in Yemen.

• Young U.S. citizens may be kidnapped or trafficked for forced marriage. Family members in the United States or Yemen are often involved in these kidnappings.
• The Houthis control Sana’a. They have detained U.S. citizens without cause, including some with dual citizenship.
• U.S. citizens have faced difficulty and delays when trying to leave Yemen.

Landmines

Landmines and unexploded ordnance exist throughout Yemen. Their location is often not marked or easy to recognize.

• They offer tourist trips with unofficial and invalid "visas."
• These companies put tourists in danger and legal jeopardy.
• Only the Republic of Yemen government can issue valid Yemeni visas.

The U.S. government cannot help U.S. citizens in Socotra.

Aviation safety

Limited commercial flights are available from Aden to other airports in the region. Sana’a International Airport is closed for commercial flights as it is frequently the target of attacks due to its
