Central African Republic ceasefire in tatters after clashes

The Central African Republic's Muslim rebels and Christian militia accused each other on Tuesday of violating a ceasefire deal signed last month, following days of clashes in the country's remote north.

The signing two weeks ago in the neighboring Congo Republic raised hopes of a political solution to sectarian violence that has killed thousands and displaced more than a million people since the Muslim Seleka fighters seized power in March 2013.

The Christian "anti-balaka" took up arms in response to a wave of abuses by Seleka fighters once in power last year, pushing the rebels back northward. Tens of thousands of Muslims fled militia violence into the Seleka-controlled enclave.

Ukraine keeps up anti-rebel offensive with nervous eye on Russia

Ukrainian government forces, backed by warplanes, kept up a military offensive to claw back lost territory from pro-Russian separatists on Tuesday while casting a nervous eye at Russian military exercises over the border.

Kiev's military said government forces had clashed 26 times with separatists in the Russian-speaking east in the 24 hours up to Tuesday morning, while fighter jets had struck at rebel positions and concentrations of military equipment.

But it acknowledged that separatist forces had pushed it out of Yasynuvata, a railway junction near the main rebel-controlled city of Donetsk that it seized from separatists on Sunday.

Hundreds of troops deployed in Sierra Leone and Liberia on Monday to quarantine communities hit by the deadly Ebola virus, as the death toll from the worst-ever outbreak reached 887 and three new cases were reported in Nigeria.

With healthcare systems in the West Africa nations overrun by the epidemic, the African Development Bank and World Bank said they would immediately disburse $260 million to the three countries worst affected - Sierra Leone, Liberia and Guinea.

The World Health Organization, which warned last week of catastrophic consequences if the disease were not controlled, reported 61 new deaths in the two days to Aug. 1 as the disease continues to spread.

Second Ebola patient arrives in U.S. for more treatment

A plane carrying a second American aid worker infected with Ebola from West Africa arrived in Maine to refuel on Tuesday and was due to continue to Atlanta so the woman can receive further treatment for the deadly virus.

Missionary Nancy Writebol, 59, departed from Liberia on Monday in a medical aircraft. She was aboard a plane that landed at Bangor International Airport in Maine just after 8 a.m. EST (1200 GMT) on Tuesday, television station WCSH of Portland, Maine, reported. The station carried live coverage of the plane stopping to refuel at the airport.

Writebol's arrival came a day after Mount Sinai Hospital in New York City said it was testing a man who traveled to a West African nation where Ebola has been reported. He arrived at the emergency room on Monday with a high fever and a stomach ache, but was in good condition, hospital officials said.

Four players Man Utd must cull – and one who should survive

Louis van Gaal says he will inform his Manchester United players which of them are free to leave the club after tonight's friendly against Liverpool, but I think he will have made his mind up a long time ago.

[VAN GAAL SET FOR SHOWDOWN TALKS]
The papers have been full of speculation as to which names will be for the chop, so here’s my pick of four players who need to go, and one who should have a stay of execution.

NANI: OUT
I just think he is too inconsistent for a top club. He has the ability but it just appears that he doesn’t want it badly enough. He wants to do a few stepovers and a few backheels but that isn’t how you win things, is it? When he is at it he has been very pleasing on the eye but his big performances are too few and far between.
