Greece’s foreign minister Nikos Dendias arrived in Turkey on Sunday in a show of support, the ministry said, despite a longstanding rivalry between the two Nato countries.

Dendias was met by his Turkish counterpart Mevlut Cavusoglu, according to footage on state-run ERT TV, before they boarded helicopters to visit the quake-hit regions, Agence France-Presse reports.

His arrival marks the first visit by a European minister to Turkey since the earthquake.

The two ministers are travelling to Antakya, where Greek rescuers are helping with search and rescue operations.

The ministry said he will also visit members of the Greek Aid Mission in the country.

So far, the Greek government has sent 80 tonnes of medical and first aid equipment.

According to the ministry, the foreign minister will also discuss ways Greece can give further assistance to Turkey.

As the rescue efforts continue following the devastating earthquakes in Turkey and Syria, here is a summary of recent events.

• UN emergency relief coordinator Martin Griffiths said the death toll from the earthquake is likely to “more than double”, adding that he expected tens of thousands more deaths. He visited the Turkish province of Kahramanmaraş on Saturday, describing the earthquake as the “worst event in 100 years in this region”

• Search operations continue, and in Turkey’s southeastern province of Hatay, a Romanian rescue team carried a 35-year-old man named Mustafa down a pile of debris from a building, broadcaster CNN Turk said, about 149 hours after the quake.

• A spokesman for the UN secretary-general has told the BBC it was time “to put all politics aside” to deliver aid to Syria, Stéphane Dujarric, spokesperson for the UN secretary-general, António Guterres, added that it was “hard to imagine a more complex emergency” in Syria.

• The European Union’s envoy to Syria urged Damascus not to politicise issues of humanitarian aid, rejecting accusations as “unfair” that the bloc had failed to provide sufficient help to Syrians. “It is absolutely unfair to be accused of not providing aid, when actually we have constantly been doing exactly that for over a decade and we are doing so much more even during the earthquake crisis,” Dan Stoenescu told Reuters.
