DHAKA: A bomb has killed at least two people, including a police officer, and injured at least 10 more people at a rally in Ukraine’s second city Kharkiv.

The rally was one of several being held to mark a year since the Kiev uprising that led to the fall of pro-Russia leader Viktor Yanukovych, reports the BBC.

Security forces have detained four suspects in the attack, officials say.

Kharkiv lies outside the conflict zone in eastern Ukraine, where a ceasefire appears finally to be taking hold.

The government has agreed to start pulling back heavy weapons from Sunday, and the rebels said they would start the process on Tuesday.

The pullback will not be completed until at least 8 March, five days later than the deadline set at peace talks in Minsk this month.
