The US Federal Aviation Administration (FAA) issued the alert warning of longer-range missile test launches prior to the end of 2019, or in the early part of 2020, US broadcaster ABC News said Monday, citing a threat analysis it obtained from the FAA. South Korean and US officials are on alert this week for a potential long-range missile test, it added.

The ABC report also raised the possibility that North Korea may test its solid-fuel rocket or a sea-based ballistic missile, adding that launching a long-range missile would put them at risk of souring ties with China and Russia, and pressure US President Donald Trump to take a hard-line approach.
