That concludes our live blogging for Tuesday, January 6.
State Department Spokeswoman Jen Psaki on Ukrainian pilot Nadiya Savchenko, who is being held by Russia and whose hunger strike is entering the fourth week:
"We welcomed the exchange of some detained persons in December; hundreds remain in captivity. We reiterate our condemnation of Russia's continued detention of Ukrainian hostages inside Russia, including a Ukrainian member of Parliament, Nadiya Savchenko, and film producer Oleg Sentsov. We understand that Ms. Savchenko is on a hunger strike to protest the terms of her detention and is suffering additional health problems. We call for her immediate release, as well as other Ukrainian hostages held by Russia."
Handle with care.
