 "Grenade explodes during Ukraine clashes; 1 officer killed")
A grenade exploded outside Ukraine's parliament during a nationalist protest against a vote to give greater powers to separatist regions in the east, killing one police officer, the interior ministry said.
About 100 other officers were injured in the clashes, 10 of them seriously.
Some of the officers were injured in the blast. One of them died from shrapnel wounds, Interior Minister Arsen Avakov said.
The protesters were carrying sticks and truncheons. Some of them were masked.
Kiev mayor Vitali Klitschko described the clashes as "a bloody provocation" and called for the prosecution of the attackers.
Avakov said that about 30 people have been detained, including the person who threw the grenade.
The decentralisation of power was a condition of a truce signed in Minsk in February aimed at ending the fighting between Ukrainian government troops and Russia-backed separatists that has left more than 6,800 dead since April 2014.
But some Ukrainians oppose changing the constitution, saying that it would threaten the country's sovereignty and independence.
A total of 265 deputies in the 450-seat parliament gave preliminary approval Monday to the changes proposed by President Petro Poroshenko. Three parties that are part of the majority coalition in parliament, however, opposed the constitutional changes.
"This is not a road to peace and not a road to decentralization," said the leader of one of those parties, former Prime Minister Yulia Tymoshenko. "This is the diametrically opposite process, which will lead to the loss of new territories."
Parliamentary speaker Vladimir Groisman denied that the changes would lead to the loss of the Donetsk region, where there have been clashes with separatists.
"There is no hint of federalism. Ukraine was, is and will be a unified state," Groisman said.
With the decentralization bill, Poroshenko, who is due to address the nation Monday night, found himself in a tight spot. While Ukrainian nationalists fear that the bill would incite separatism, Russia-backed rebels in the east and Moscow say the bill doesn't give regions enough powers and is short of the pledges Kiev made in Minsk.
