Zimmerman told the court that he traveled to Russia to meet a woman he had previously contacted online and that he had the gun for self defense, unaware of Russian laws, according to the court' press service statement. He has fully admitted guilt, the statement said.
Zimmerman's sister Robin Stultz said her brother was intercepted while sailing in international waters with "absolutely no intention to enter Russia."
"He was sailing from the U.S. to New Zealand, so of course he had a firearm on board," she told the AP in a statement. "You can't just call 911 if something goes wrong out at sea. He voluntarily disclosed it to them and they charged him with arms smuggling. This is an obvious set-up to get another American they can trade. He needs to be declared wrongfully detained," Stultz said.
She added: "I wouldn't trust any 'confession' the Russians claim he's given. He hasn't been able to meet with anyone from the U.S. Embassy since his arrest."
There was no immediate comment from U.S. officials.
