The Ukrainian government has said its websites and banks have been hit by cyber attacks. Two state-owned banks, PrivatBank and Oschadbank, had been targeted by “massive” denial of service attacks and other failures which interrupted banking services.

Earlier this month, after years of delay, a deal was signed by the French energy giant Total Energies giving the green light to a controversial pipeline running from Uganda to Tanzania.

A new study has found that a quarter of the world's rivers contain potentially toxic levels of pharmaceutical drugs and it's been concluded that the pharmaceutical products found in them are a threat to human health and aquatic life. We get details from Dr Veronica Edmonds Brown, an Aquatic Ecologist at The University of Hertfordshire.
