Protests broke out across Europe a day after twin blasts targeted a peaceful rally in Ankara, killing nearly 100 people, media reports said on Sunday.

Even as the official death toll stood at 95, some media posts claimed it to be way more than it. The suspected suicide terror attack had killed mostly Kurds on Saturday morning outside a railway station in the national capital, Ankara.

Turkey's pro-Kurdish Peoples' Democratic Party (HDP), one of the groups that had called for the Saturday's peace rally, said in a Twitter post that 128 people have lost their lives and 516 people were injured the attack. The government has not confirmed the figures.

In Paris, thousands of people marched to the city's Place de la Republique on Saturday afternoon, condemning the ghastly attack. The Kurdish Democratic Council (KDC) -- a Kurdish group based in France -- had called for the demonstration.

The KDC said in a statement that it "strongly condemns this cowardly and disgusting attack".

More that 400 marchers came out on the streets in Strasbourg in northeastern France, while hundreds of people came out in solidarity with the terror attack victims in the southern city of Marseille, with some holding signs reading "Murderer Erdogan".

In Zurich, over 1,000 people demonstrated at the city centre, holding signs "Stop state terror in Turkey".

In Istanbul, an estimated 10,000 people marched down the city's main central avenue to protest the attacks.

Turkish Prime Minister Ahmet Davutoglu told reporters there were "very strong signs" that the attacks were carried out by suicide bombers. The country has announced a three-day mourning following the deadliest attack in the history of modern Turkey.

The twin blasts also upped tensions ahead of Turkey's 1 November snap polls. The country was already witnessing hostility over an offensive on Kurdish militants by the government forces.
