Turkey claims migrant killed in Greek border clash
Turkish officials have said a man was fatally wounded when Greek security forces opened fire as migrants gathered at the border on Wednesday.
Greece immediately issued a flat denial, saying it was not involved in any such incident involving gunfire.
Thousands of people have headed to the border after Turkey said it would no longer stop migrants crossing.
Greece has also denied claims that two Syrians were fatally shot while trying to cross the border last night.
What happened at the border?
Videos taken close to Turkey's northern border with Greece on Wednesday showed dozens of migrants hurrying through a field, escaping tear gas. Several men are seen carrying a man in a blanket holding his head.
One of the men, speaking in Farsi, is heard on a video saying Greek soldiers had fired at their legs and that five migrants were wounded.

The local authority in the nearby town of Edirne then issued a statement saying one migrant had died in hospital and five had been wounded. It accused Greek police and border units of opening fire on migrants in no-man's land between the Greek border gate at Kastanies and the Turkish gate at Pazakule.
Greek government spokesman Stelios Petsas was adamant there had been "no such incident with fire from the Greek authorities" and accused Turkey of "creating and spreading fake news".
Three men from Afghanistan and Senegal have told the BBC's Jonah Fisher of an earlier incident on Tuesday night in which they said they saw two Syrians fatally shot in the neck and head.
The men said it happened as they tried to cross the river which acts as a border at Ipsala, some 120km (75 miles) south of Edirne.

Greek authorities told the BBC that no migrants had either been killed there or injured.
How it started
When at least 50 Turkish soldiers were killed in northern Syria in late February, President Recep Tayyip Erdogan said Turkey was facing a major influx of people fleeing Russian and Syrian air strikes and that it could not handle another wave of refugees.
Turkey already has 3.7 million refugees from the conflict in Syria, but after the European migrant crisis in 2015 it signed a deal with the EU to stop more migrants heading into Greece.
Although the EU promised billions more euros in aid, Turkey was unimpressed and decided to open its borders with Greece and even bussed migrants close to the north-western border.

Greece says that since Saturday it has prevented 27,823 migrants from coming into the country illegally and arrested 220 people.
President Erdogan argued on Wednesday that the decision to open the border gates was "fully" in line with international law, and he accused Greece of "inhumane scenes" over a video on Monday showing Greek coastguards firing into the sea near a migrant dinghy.
The coastguards barred the migrants from coming any closer although other dinghies managed to get through.
A Greek navy ship docked in Lesbos on Wednesday and officials say it will take 500 people who have arrived on the island since the start of the month.
Top EU officials have visited the area, which serves as the bloc's south-eastern border, promising financial help to the Athens government to step up security.
European Commission President Ursula von der Leyen described Greece as a "European shield", using the Greek world aspida.
Prime Minister Kyriakos Mitsotakis said Greece could not and would not be "blackmailed".
EU interior ministers were due to discuss the rising tensions on the border later on Wednesday, and Greek reports said they would agree "all necessary measures" to put a stop to illegal border crossings.
