George Zimmerman, the man who was cleared of murder after he shot dead the unarmed black teenager Trayon Martin in Florida four years ago, is persisting with efforts to auction the gun used in the killing. It was removed from one auction site, which said it wanted no part in the listing, but it's now up for sale on a different site. David Willis reports. “The killing of Trayvon Martin in a gated community on the outskirts of Orlando sparked protests which gave rise to the Black Lives Matter movement, and prompted a national debate about race relations in America. George Zimmerman maintained he acted in self-defense after the teenager attacked him in the street, something Trayvon Martin's family strenuously denies. Now, after another website refused the posting, Mr. Zimmerman has put the gun up for auction on a site called Unitedgungroup.com with a starting price of 5,000 dollars.”

US officials have explained why an American delegation walked out of the inauguration ceremony of Uganda's President Yoweri Museveni. Several European and Canadian diplomats also left abruptly when Mr. Museveni made disparaging comments about the International Criminal Court. The US State Department Spokeswoman Elizabeth Trudeau said the presence of Sudan's leader President Omar al-Bashir, who's wanted by the ICC on charges of genocide, was also an issue. “In response to President Bashir's presence and President Museveni's remarks, the United States delegation along with representatives of the European Union countries and Canada departed the inauguration ceremonies to demonstrate our objection. We believe the walking out in protest is an appropriate reaction to a head of state mocking efforts to ensure accountability for victims of genocide, war crimes and crimes against humanity.”
