I don't know how these hackers gained access to the accounts of people in the high ranking of the society. I remember it also happens to some of the celebrities Twitter accounts. This is something that needs to be focused on for all the social media platforms.
This kind of Tweets will somehow teach the people not to trust immediately especially If it happens like out of the blues without any previous Tweets about these.
Yes we really not to be quick after getting a social comments cause the account could be hacked before that .Here we have faced same thing that his account hacked and after that we have seen a tweet so we need to more careful on that and also try to get the news from different source if it correct we can surely get it on other site as well .However we don't get any others source that he really said it so it's not good for us to become excited .I hope the government will think more and make strategy to switch it properly on the country .I didn't shock much after getting this news cause i knew it could be happen something like this .So i wanna suggest you to research and being updated always with the news what we get .
