Geo quiz

Now, a national holiday is one of the clues to our geo quiz. We are looking for an East African country marking 50 years of independence today. On July 1st 1960, two territories that had been administered by the UK and Italy joined together to become one republic. It would take another 2 decades to complete a constitution. The legal system relies on a mix of English and Italian laws, and Islamic sharia. In 1991, this country’s president was ousted by armed clans; civil war began.
And there’s still fighting. Government troops today are battling Islamic militants. So where is this troubled country bordered by Kenya and Ethiopia?
