The US and Australian embassies in Malaysia have warned of a potential terrorist attack at a popular hawker street in Kuala Lumpur. The US Embassy issued an advisory saying it has credible threat information and urged its citizens to avoid Alor Street, located in a shopping belt in the city center, and its immediate surrounding areas. It said that terrorist organizations had in the past planned attacks to coincide with significant dates, but it gave no details. The Australian Embassy issued a similar alert based on the US warning. Malaysia has arrested more than 100 ISIS supporters in the past two years, some of whom were allegedly plotting attacks in the country. They included civil servants and members of security forces.
