Iran's president on Wednesday called his country's decision to dramatically increase its uranium enrichment after saboteurs attacked a nuclear site "an answer to your evilness," saying Israel hoped to derail ongoing talks aimed at reviving Tehran's tattered nuclear deal with world powers.

Meanwhile, the head of the World Health Organisation said coronavirus cases are continuing to rise globally at worrying rates and noted that the number of new cases confirmed per week has nearly doubled during the past two months.

At a press briefing on Friday, WHO Director-General Tedros Adhanom Ghebreyesus said the number of new cases is approaching the highest rate of infection that we have seen so far in the pandemic.
