MOSCOW (Reuters) - An intruder smashed a bottle containing a chemical fluid in the campaign office of allies of Kremlin critic Alexei Navalny in the Russian city of Novosibirsk on Tuesday, forcing them to evacuate the premises, opposition activists said.

Two people were treated by medics and at least one was taken to hospital, said Sergei Boyko, an opposition politician and ally of Navalny, who is being treated in hospital in Germany after what Berlin said was an attempt to kill him by poisoning.
