It listed +44 7341 185777 as an emergency telephone number, accessible via WhatsApp, for Kyrgyz citizens. Kazakhstan’s embassy has issued similar advice, saying there are emergency contact lines for Kazakh citizens in the United Kingdom as well as their relatives in Kazakhstan. Hundreds of people have been arrested in violence that police say was stirred by agitators promoting anti-immigrant sentiment. Despite fears of more unrest, Wednesday night was relatively peaceful as thousands of police officers and anti-racism protesters mobilized to head off the threat.
