The U.N. Security council will hold an urgent meeting today to discuss North Korea’s latest ballistic missile launch and calls from the United States for more sanctions on Pyongyang.

The United States, Japan and South Korea requested the meeting to address Pyongyang’s launch of what appeared to be an intercontinental ballistic missile which Japan said probably fell within its exclusive economic zone.

Speaking in Washington, US Secretary of State Rex Tillerson called for “additional measures” to toughen up sanctions, including allowing countries to intercept vessels carrying goods to and from North Korea.

The council was already scheduled to discuss progress in implementing three recently-adopted rounds of sanctions aimed at choking off revenue to Pyongyang’s military programs.

Since November last year, the council has slapped export bans on coal, iron, lead, textiles and seafood, restricted joint ventures and blacklisted a number of North Korean entities in response to the country’s missile and nuclear tests.

It has also banned the hiring of North Korean guest workers and capped oil exports, in particular from china, Pyongyang’s main trading partner.
