DAKAR, Senegal (AP) — No one knows for sure just how many people Patrick Sawyer came into contact with the day he boarded a flight in Liberia, had a stopover in Ghana, changed planes in Togo, and then arrived in Nigeria, where authorities say he died days later from Ebola, one of the deadliest diseases known to man.

A US judge gave the go-ahead for the $2 billion sale of the Los Angeles Clippers to former Microsoft chief executive Steve Ballmer, ruling that embattled owner Donald Sterling could not block the move. The ruling by California Superior Court Judge Michael Levanas on Monday came after a three-week trial pitting the 80-year-old Sterling -- barred from the National Basketball Association for life for making racist remarks -- against his estranged wife Shelly, who made the deal with Ballmer. Levanas said the sale could go forward immediately, even if Donald Sterling -- who had challenged his wife's authority to sell the NBA franchise -- appeals. Shelly Sterling negotiated the sale on behalf of the family trust, after Donald Sterling's position as co-trustee was terminated when two medical experts declared the billionaire real estate mogul mentally incompetent to handle trust affairs.

Prime Minister David Cameron on Tuesday set out new welfare rules to cut European migrants' access to social security payments, marking the latest in a string of British measures aimed at addressing voters' concerns over immigration. Writing in The Daily Telegraph newspaper, Cameron said that from November migrants coming to Britain from the European Union to find work would be entitled to claim unemployment and child benefits for three months, rather than the previous six months. Opinion polls show immigration is one of voters' biggest concerns going into a national election in 2015, fuelling a rise in eurosceptic sentiment that has helped the anti-EU UK Independence Party (UKIP) draw voters away from Cameron's Conservatives. In a bid to stop voters defecting, Cameron has said he wants to cut net migration and has targeted those who he says come to Britain solely to tap its benefit system.
