MOSCOW, April 21 (Reuters) - Police detained 102 people at protests across Russia in support of jailed Kremlin critic Alexei Navalny on Wednesday, the OVD-Info protest monitoring group said.
The arrests came on the same day that President Vladimir Putin delivered a state-of-the-nation address in which he warned the West not to cross Russia's "red lines", saying Moscow would respond swiftly and harshly to any provocations and those responsible would regret it.
