The United States is warning of a terrorist attack that may unfold in Nigeria’s capital Abuja.

According to the US embassy in Nigeria, “there is an elevated risk of terror attacks in Nigeria, specifically Abuja. Targets may include, but are not limited to, government buildings, places of worship, schools, markets, shopping malls, hotels, bars, restaurants, athletic gatherings, transport terminals, law enforcement facilities, and international organizations.” The embassy added that it would offer reduced services until further notice. In addition, the United Kingdom warned of similar attacks saying “there is an increased threat of terrorist attack in Abuja. Attacks could be indiscriminate and could affect western interests, as well as places visited by tourists.”

These warnings come as Nigeria has been in a war against terrorists who have their sights on overthrowing the government and creating a caliphate. Currently, terrorist organizations like the Islamic State control regions in the northeastern part of the country, where they often attack government personnel and civilians.

Over the last year, multiple attacks have occurred in Nigeria, including a prison raid in the capital city which freed approximately 440 inmates, some of whom were ISIS fighters and bomb makers.
