(Reuters) - Iran said on Tuesday it planned to build its first nuclear-powered submarine, a news agency reported, an announcement that came days before talks with world powers and may add to Western concerns over its atomic activities.

Next nuclear talks - Iran vs.(?) UNSC P5+1 is in Moscow, 18-19th.

All these rather instigating diplomatic jabs - are they all approved by Khamenei? - consistent indication of how he approaches and thinking. Or rather out of coordination.
