The following are the latest developments in the Ukraine crisis:

Putin signed a decree on the partial mobilization in Russia, the Kremlin said Wednesday, which the president said in a televised address that a partial mobilization is necessary to defend Russia's sovereignty and territorial integrity.

According to the decree, the partial mobilization in the Russian Federation will begin on Wednesday.

"... To protect our motherland, its sovereignty and territorial integrity, to ensure the security of our people and people in the liberated territories, I consider it necessary to support the proposal of the defense ministry and the general staff on the conduct of partial mobilization in the Russian Federation," Putin said.

"... Citizens of the Russian Federation called up for military service by mobilization have the status of military personnel serving in the Armed Forces of the Russian Federation under a contract," said the decree.

According to the president, only citizens in military reserve will be subject to prescription, and they will undergo additional training.
