The death toll from violent protests in Ukraine has risen to three after two more National Guard officers died from injuries suffered in a grenade explosion.
In the worst outburst of violence in Kiev since the new government took power in 2014, nationalist protesters clashed with police and National Guard troops outside Ukraine’s parliament on Monday as politicians took up a measure to give greater powers to Russia-backed separatists in eastern Ukraine.
About 140 people were taken to hospital, most of them law enforcement officers, the interior ministry said.
One National Guard officer died on Monday, and a second died early today, both as a result of injuries caused by the grenade, interior minister Arsen Avakov said.
The National Guard reported another death in the early afternoon, saying that the third man died after a day in a coma.
Most of the 100 violent protesters were members of Svoboda, a nationalist party that holds only a handful of seats in parliament.
Wielding truncheons, pipes and sticks with nails, they faced off against police carrying shields and truncheons.
About 30 protesters were detained, of whom 18 remained in custody, including the man suspected of throwing the grenade.
Mr Avakov said he was a Svoboda member who fought in the east in one of the volunteer battalions, which are loosely controlled by the government.
President Petro Poroshenko, on a hospital visit to see the injured officers, pledged to find the organisers of the clashes who were handing out sticks and weapons like grenades.
The decentralisation of power was a condition demanded by Russia for a truce signed in Belarus in February aimed at ending the fighting between Ukrainian government troops and Russia-backed separatists that has left more than 6,800 people dead since April 2014.
But Ukrainian nationalists strongly oppose the constitutional changes, saying they would threaten the country’s sovereignty and independence.
Mr Poroshenko and his supporters insist that the constitutional amendment would devolve powers to local communities in all of Ukraine, from east to west, while making sure that Ukraine stays a unitary state.
While Ukrainian nationalists think the amendment gives too much power to the regions including the east, Russia-backed rebels there say it is not enough.
Speaking to Russian news agencies in Donetsk, rebel leader Alexander Zakharchenko criticised Mr Poroshenko for taking out a clause that could offer sovereignty to the east and make it a part of a loose confederation within Ukraine.
Now that 265 politicians have given it preliminary approval, the bill comes up for the final vote where Mr Poroshenko will need to get at least 300 votes.
A truce in eastern Ukraine brokered by Western powers in February helped to subdue the fighting but did not stop it completely.
Government troops and separatists agreed last month to stop fighting by today which is the first day of school in Ukraine.
Both sides said that the ceasefire is holding despite sporadic exchange of rifle fire.
