Ukraine police clashes with protesters demanding constitutional changes

A crowd of protesters seeking constitutional change clashed violently with police in central Kiev Tuesday morning.

The protesters attacked police with Molotov cocktails outside the parliament building. 

Police responded with stun grenades and tear gas to push the crowd back.

The confrontation came the same day as parliament delayed a discussion of changes that would limit the powers of the president.

The unrest marked the latest wave of clashes between demonstrators and riot police in the almost three-month-long political standoff, which began last November as peaceful demonstrations calling for the country’s European integration.
