SEOUL (Reuters) - North Korea said on Monday that it would put on trial two detained American tourists for crimes against the state.

"Their hostile acts were confirmed by evidence and their own testimonies," said the official KCNA news agency, referring to U.S. citizens Jeffrey Fowle and Matthew Miller who are being held by the isolated country.

Another U.S. national Kenneth Bae, a Christian missionary who had been arrested in November 2012, was convicted and sentenced to 15 years hard labor last year.
