Russia: 125,000 people involved in Moscow and Petrograd political strikes (20 leaders arrested February 10-11).
United Kingdom: King opens Parliament. Petrol licence issues suspended, private motoring virtually eliminated (331,897 licences in 1916).

South America: Governments of Brazil and Argentina threaten to sever relations if Germany attacks their shipping.
