Reuters quotes from a Ukrainian regional prosecutor's online statement:
"According to eyewitness accounts the explosive device was thrown from a passing car," the statement said.
There are rumors, including the usually reliable @kevinrothrock, that "suspects" in the Kharkiv bombing have already been detained.
Choice to use the term "our guys" certainly a bizarre one.
Is it just us, or does Ukrainian President Petro Poroshenko's Twitter feed seem unfathomably oblivious to the tragedy in Kharkiv?
Via AFP:
Regional prosecutor Yuri Danilchenko said two people died, one of them a police officer, revising down an earlier toll of three killed.
"It was a homemade bomb packed with shrapnel, put in a plastic bag and hidden in snow by the side of the road," he told reporters.
