North Korea launched three short-range missiles, presumably Scuds, from its east coast early Tuesday morning, the South Korean Joint Chiefs of Staff said in a report by the Chosun Ilbo.

The launches, which took place around 5:45 a.m. to 6:40 a.m. Korean Standard Time, come following Washington and Seoul’s announcement last week that allies would install a THAAD anti-missile battery in South Korea, something the North later said would become a possible target for a nuclear strike.

The missiles were reportedly fired from North Hwanghae Province at a range of about 500 – 600 kilometers, a distance far enough to cover from Seoul to Busan.
