President Obama has directed US Federal authorities to take more steps to make sure American health services adhere to the proper safety procedures to deal with suspected Ebola patients. Mr. Obama issued the directive as US officials confirmed that an unidentified nurse caring for a Liberian man who died from Ebola had tested positive for the disease in Texas. From Dallas, Alistair L.

The US Centers for Disease Control and Prevention called it a breach in protocol. The nurse could not pinpoint any specification while she might be infected. An investigation has been launched to assess procedure at the hospital. Health authorities say the nurse identified the symptoms herself and it's in the early stage of the illness. She was quickly brought to the hospital's isolation unit. Her apartment is now being disinfected. Screening has started at the J.F.K. Airport in New York, and will follow up at four other US airports where most passengers from Ebola-stricken countries arrive.

Donors at a conference in Cairo have pledged 5.4 billion dollars for Gaza, half of it is to repair the damaged dam by 50 days of war with Israel this year. The total was a billion dollars more what the Palestinian president Mahmoud Abbas has asked for. Speaking in Cairo, the US Secretary of State John Kerry said it was now time for a long-term peace plan.

The United States, President Obama, myself, our whole country are deeply committed to the possibility, to the need, the urgency of having two states that live side by side, two peoples living in peace, Palestinian and Israeli. But it is up to the leaders; both leaders must make the decision that they are prepared to come back and negotiate in order to achieve the peace that everybody in this region hopes for.

Mr. Kerry also spoke about Syria, saying he was very concerned about reports that the Islamic State militants had made gains in the northern town of Kobani. He described the situation there as a tragedy, but said it did not defied the US-led coalition strategy to defeat the Islamic State.

Reports from Iraq say the number of people killed in a triple-suicide-bombing in the Kurdish town of Karatapi has risen to at least fifty. Many of those who died were enlisting to fight the Islamic State militants. Jim Muir reports.

First one bomber with a suicide belt blew up himself up at the entrance, then two more in cars packed with explosives followed, causing mayhem and carnage. IS said the bombers were foreign jihadists. The attacks showed that despite its preoccupation with the battle at Kobani, far off from the Syrian boarder with Turkey, IS is still capable of striking in widely different parts of Iraq.

At least eight people have been killed in the Somali capital Mogadishu in a car bomb explosion outside a cafe in the center of the city. The Imoro Cafe which is popular with politicians is about 500 meters from the parliamentary building. The security forces have said they believed the Islamist militant group Al Shabaab was behind the explosion.

Students at several major universities in the Egyptian capital Cairo have staged anti-government protests, calling for the release of fellow students detained by government. Police backed by armoured vehicles broke up the protests arresting several students. The protests were organized by supporters of the ousted president Mohammed Morsi.

The influential Brazilian environmentalist Marina Silva who came third in last Sunday's presidential election has backed the Opposition's centrist candidate Aecio Neves in the second round. The announcement is seen as a blow to President Dilma Rousseff who is running for a second four-year term. Here is Bora Davis.

Her own dream of becoming Brazil's first black environmentalist president might not have been realized. But in a country where voting is compulsory, the 20 million or so votes that Marina Silva secured in the first round are being actively courted by the two remaining candidates. Mrs. Silva was widely expected to publicly support the Centrist business-friendly Aecio Neves, even though she is probably more ideologically close to the incumbent president Dilma Rousseff. But Dilma's attacks against Marina's policies and her record in the run-up to the first round of voting meant a wrap push Ma was never really on the cards.

Polls are due to close about now in Bolivia's presidential elections in which the incumbent Evo Morales is expected to win a third consecutive term in office. More than six million people have voted. The electoral authority said the voting went ahead without major incidents.
