PARIS (Reuters) - French investigators believe a Frenchman detained in Ukraine with a cache of weapons and explosives was more likely involved in arms smuggling than tied to a militant group, the prosecutor leading the case said on Tuesday.

France has requested Kiev's cooperation but is still awaiting a response more than 24 hours after Ukraine's state security service (SBU) said the suspect had planned "terrorist attacks" during the Euro 2016 football tournament which kicks off on Friday in France.
