The UN atomic watchdog cannot yet determine if a building in a remote site in the Syrian desert destroyed by Israeli planes last year was intended for nuclear use, the IAEA found in a report Wednesday.

`While it cannot be excluded that the building in question was intended for non-nuclear use, the features of the building ... along with the connectivity of the site to adequate pumping capacity of cooling water are similar to what may be found in connection with a reactor site,` the IAEA said in a restricted report, a copy of which was obtained by AFP.
