Prosecutors say a grenade was lobbed and exploded at the house of the outgoing governor of Moldova's central bank. There were no casualties.

Prosecutors said windows were broken and the house's exterior was damaged in the attack which they called "an act of terrorism." It occurred early Monday while Dorin Dragutanu and his family were asleep.

Dragutanu resigned as governor of the National Bank of Moldova in September amid protests over more than $1 billion that went missing from three banks prior to elections in November 2014.

Moldova has been in political turmoil since then, and has had six prime ministers in the past year.

No successor has been appointed, and Dragutanu has remained in the post. He declined to comment on the attack.
