The US may launch unilateral sanctions against North Korea, a US special envoy for the isolated state said on Sunday, two days after it carried out its fifth and biggest nuclear test in defiance of UN sanctions.
The Philippines said on Saturday it had seized a North Korean freighter that was covered by harsher United Nations' sanctions against Pyongyang over its nuclear programme.
The UN Security Council is considering imposing further sanctions on North Korea after it carried out a nuclear test, the British ambassador said Wednesday.
