Moldova’s political crisis has escalated, with the interim president dissolving parliament and calling snap elections on 6 September.
But the parliament declared the move illegal, saying the country’s state institutions had been seized.
The stalemate follows February’s polls, where no clear winner emerged between rival pro-EU and pro-Russian parties.
Sunday’s move saw the Constitutional Court sack Russian-backed Igor Dodon in favour of pro-EU former PM Pavel Filip.
There are now fears that the prolonged political crisis could lead to violent clashes on the streets.
Moldova, a former Soviet republic, lies between the EU member state Romania and Ukraine and is one of Europe’s poorest countries.
What’s happening in Moldova?
On Sunday, the Constitutional Court in the capital Chisinau relieved Mr Dodon of his duties because of his refusal to dissolve the parliament.
This comes a day after the pro-EU Acum political bloc and Mr Dodon’s Socialists struck an unlikely deal and formed a compromise government.
In parliament, lawmakers also declared that Moldova’s state and legal institutions “have been seized” by influential oligarchs, calling for the resignation of several top officials.
But their opponents say the formation of the new government took place a day after a constitutional deadline for this expired – a claim both Acum and the Socialists dispute.
Mr Filip’s Democratic Party – which is led by Moldova’s richest man Vladimir Plahotniuc – later filed a legal challenge which was backed by the Constitutional Court.
In response, Mr Dodon described this as desperate steps to usurp power.
Is this political tug-of-war unusual?
No. In Moldova, a parliamentary republic, the rival political camps frequently clash with one another.
Therefore the country – where the electorate is split between EU- and Russia-sympathisers – has witnessed several such crises in recent years.
They usually end up in holding snap elections, but results are often inconclusive.
