At least five students and a security guard have been shot and killed in a dawn attack at a secondary school in northern Kenya. The attack was allegedly led by a former student who had been suspended, the school's head teacher said. He is accused of returning to dormitories at the school in Lokichogio on Saturday with two accomplices. As well as killing six people, witnesses say they raped two girls and injured another 18 students. According to the head teacher, the boy - said to be from nearby South Sudan - had fought with another pupil, leading to his suspension. He returned to find the boy, but he was not at the AIC Lokichogio Secondary School at the time. Turkana County Commissioner Seif Matata  told Kenya's Daily Nation newspaper that the suspect "was heard telling fellow students that he is going to burn the school or he will come back and avenge because of the suspension". The Kenya Red Cross says they have evacuated the injured. Source: www...

A plane from South Africa is expected to touch down in the new airport, ending the island's reliance on a ship once every three weeks. It is hoped the service, funded by the UK, will boost tourism and help make St Helena more self-sufficient. But British media have dubbed it "the most useless airport in the world". Built with £285m ($380m) of funding from the UK Department for International Development (Dfid), it should have opened last year but dangerous wind conditions delayed the launch. After further trials this summer the weekly service between Johannesburg and St Helena was passed as safe.

Media caption Hassan Rouhani: "Iran will not surrender." Global powers, including key US allies, have said they will stand by the Iran nuclear deal which US President Donald Trump has threatened to tear apart. Mr Trump said on Friday that he would stop signing off on the agreement. The UK, France and Germany responded that the pact was "in our shared national security interest". The EU said it was "not up to any single country to terminate" a "working" deal. Iran's President Hassan Rouhani said the US was "more isolated than ever". "Can a president annul a multilateral international treaty on his own?" he asked. "Apparently he doesn't know that this agreement is not a bilateral agreement solely between Iran and the United States."
