Two of the world's most baseball-obsessed nations declared an end to a half-century of hostility six months ago, raising hopes of warmer ties between the home of the Major Leagues and the source of some of its best talent.

Ministers are to consider the 'nuclear option' of closing the Channel Tunnel at night if the Calais migrant crisis deepens, it has been reported. Details of the proposal emerged following the arrest of a Sudanese migrant who evaded French security and ran almost the entire length of the 31-mile tunnel before being caught in Kent. Abdul Rahman Haroun, 40, dodged trains travelling at speeds of 100mph before his perilous attempt was thwarted by police less than a mile from Folkestone on Tuesday. He had scaled four security fences and avoided 400 surveillance cameras before running in darkness through the tunnel - used by Eurostar trains destined for Paris and Brussels - and was only spotted when he set off an alarm 15 miles into his 'highly dangerous journey'.Government ministers have discussed closing the Channel Tunnel at nightIt comes in response to concerns about the escalating Calais migrant crisisOn Tuesday a migrant ran almost the entire length of 31-mile long tunnelAbdul Rahman Haroun, 40, dodged 100mph trains but was caught in Kent
