Amnesty International has urged Washington and London to halt arms deliveries to Saudi Arabia, which is leading a military coalition against rebels in Yemen, for the sake of saving civilian lives. In a statement released one year into the Saudi-led intervention and entitled ‘Reckless arms flows decimate civilian lives,’ the rights watchdog said that the US and UK, the largest arms suppliers to Saudi Arabia, have continued to allow transfers of the type of weapons that have been used to commit serious abuses, generating a humanitarian crisis on an unprecedented scale. The group has documented 32 airstrikes by the Saudi-led coalition since the beginning of the conflict. These strikes have violated international humanitarian law and killed 361 civilians, including at least 127 children. The World Health Organisation says that since March 2015 fighting in Yemen has killed 6,300 people, half of them civilians; the UN has warned of an unfolding humanitarian catastrophe.
