North Korea may already have the capability to deliver missiles equipped with sarin nerve agent, Japanese Prime Minister Shinzo Abe said Thursday. <br /> <br />His warning came as analysts said North Korea may be preparing for a sixth nuclear test ahead of a key anniversary in the country and following the deployment of a US naval strike group to the region. <br />"The security situation around our country is getting increasingly severe," Abe said, who was addressing the Japanese parliament's diplomacy and defense committee. <br />"We have just talked about Syria. There is a possibility that North Korea already has a capability to put sarin on warheads to strike the ground," he said. <br />Abe did not provide any evidence why he felt North Korea had the capability to equip missiles with chemical weapons.
