Volkswacht Bodensee - Refugees protest tough Greek migration policy

"Stop pushbacks, down with the government of murderers," read one of the banners at the rally in front of parliament. Another read "The blood of the innocent cries out for justice."

Some protesters carried signs with the dates of migrant boat sinkings in the Aegean Sea.

Other demonstrators drew a link between migrant deaths at sea and the February 28 train tragedy that left 57 dead and has been blamed on the government of Prime Minister Kyriakos Mitsotakis.

"Mitsotakis, you have blood on your hands -- dead kids at sea, dead kids on trains," they chanted.

Since taking office four years ago, Greece's conservative government has reinforced its land and sea borders with Turkey in a bid to stem illegal arrivals.

Police minister Takis Theodorikakos this week said a contract to build a planned 35-kilometre (22-mile) extension to the country's steel fence on the border with Turkey would be signed "in coming days".

In the latest incident in Greek waters, a woman and a man died earlier in March after a speedboat with nearly 30 people on board sank near the island of Kos.

A month earlier, a woman and a man drowned when a dinghy carrying 41 asylum seekers crashed onto a rocky coast at Lesbos island.

The European Union has said it is working with the United Nations and the African Union to organise voluntary returns to countries of origin, and to take refugees to camps before being resettled in the EU or elsewhere.

In January, European Commission chief Ursula von der Leyen said the EU planned to put in place migration deals with countries such as Bangladesh, Pakistan, Egypt, Morocco, Tunisia and Nigeria "to improve returns... and to prevent departures".

Greece has repatriated more than 8,000 people over the last two years in cooperation with the International Organization for Migration, Migration Minister Notis Mitarachi said this week.

The Greek government has consistently denied the accusations of pushbacks, despite claims to the contrary from alleged victims, rights groups and even the UN's special rapporteur on the human rights of migrants.

"In Greece, pushbacks at land and sea borders have become de facto general policy," the UN's special rapporteur on the human rights of migrants, Felipe Gonzalez Morales, said last year.
