North Korea has warned the South that it will retaliate with “physical counter-measures” if Seoul took part in sanctions by the UN.

In a statement, released a day after it announced a third nuclear test, North Korea said sanctions would mean war.

"If the puppet group of traitors takes a direct part in the UN 'sanctions', the DPRK (North Korea) will take strong physical counter-measures against it," it said.

"'Sanctions' mean a war and a declaration of war against us."

Sarah Leah Whitson, Middle East director at Human Rights Watch said:

Human Rights Watch (HRW) has accused Turkey of abusing anti-terror laws after an Istanbul court ordered the pre-trial detention of nine human rights lawyers.

The lawyers were among 12 arrested last week during early morning raids.

HRW claims that Turkey's 'overbroad' anti-terrorism laws have been used more widely to charge for non-violent political activities and legitimate exercise of rights, with charges often accompanied by prlonged pretrial detention.
