As you know, Cuba faces a new aggression against its sovereignty, dignity and attachment to the truth. The alleged sonic attacks are now the new pretext for this aggression, which justifies a policy aimed at rolling back bilateral relations between Cuba and the US. The purpose of this message is to invite you to participate in an online discussion forum that has been convened by Cuban experts and scientists to denounce the falsity of this campaign, entitled "Scientific exchange on the supposed acoustic attacks that occurred in Havana". The Forum on this topic will take place from tomorrow, November 15, 2017, from 9:00 a.m. to 3:00 p.m., Cuban time, through our website on the Internet "Red Cubana de la Ciencia", Website: https://supuestosataques.redciencia.cu. The event will continue on the 16th from 10:00 a.m.
