The U.S. and Australian embassies in Malaysia have warned of a potential terrorist attack at a popular hawker street in Kuala Lumpur.

The U.S. Embassy issued an advisory Thursday 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 says terrorist organizations had in the past planned attacks to coincide with significant dates, but gave no details.

The Australian Embassy issued a similar alert to its citizens based on the U.S. threat warning.

A police spokesman says a statement will be issued later Friday.

Malaysia has arrested more than 100 supporters of the Islamic State group in the past two years, some of whom were allegedly plotting attacks in the country.
