May says EU reponse to UK Brexit plan 'not acceptable'

British Prime Minister Theresa May said Friday the European Union's abrupt dismissal of her Brexit plan was not acceptable, as she conceded talks were "at an impasse".

"It is not acceptable to simply reject the other side's proposal without a detailed explanation and counter-proposals," May said in a televised statement from Downing Street.

"We now need to hear from the EU what the real issues are and what their alternative is so that we can discuss them."
