American Jewish journalist Simon Ostrovsky has been released by his captives, according to a statement from his employer, Vice.com.

Ostrovsky, who also has Israeli citizenship, was held by pro-Russian separatists in eastern Ukraine since Tuesday.

“VICE News is delighted to confirm that our colleague and friend Simon Ostrovsky has been safely released and is in good health. We would like to thank everyone for their support during this difficult time. Out of respect for Simon and his family’s privacy, we have no further statement at this time,” the website said in a statement.

Vyacheslav Ponomaryov, the separatist head of the eastern Ukrainian town of Sloviansk, told reporters Wednesday evening that Ostrovsky had been detained for reporting false information, Reuters reported.

Ponomaryov has appointed himself “mayor” of the town. Ostrovsky has been covering the conflict in Ukraine in recent months for the Vice.com news.

Ukraine has seen violent clashes between pro-Russian protesters and other groups since the ousting in February of the government of former president Viktor Yanukovych in a revolution which erupted over his perceived pro-Russian policies. Ukraine’s interim government has announced new elections scheduled for next month.
