Trump insisted on Friday that he meant that rock-throwers would be arrested.The tweet on the Nigerian army's Twitter account stated: "Please Watch and Make Your Deductions."The military did not return calls seeking comment on the deleted tweet.Nigeria's main Shiite Muslim movement says the army killed at least 50 of its members who were protesting this week. Nigeria's military said it killed six people and claims the protesters had fired first.* Sign up to News24's top Africa news in your inbox: SUBSCRIBE TO THE HELLO AFRICA NEWSLETTERFOLLOW News24 Africa on Twitter and Facebook.
