SALISBURY, England—A former Russian double agent convicted of treason in Moscow was critically ill in a British hospital on Tuesday after exposure to an unknown substance, with police saying it had to be “alive to the fact of state threats”.

In its first response, the Kremlin said it was ready to cooperate if Britain asked for help in its investigation of the “tragic situation”.
