Minutes away from Obama exit from Airforce 1. A Hellenic Air Force honor guard is at the Eleftherios Venizelos Airport. The US president will be received by the Greek defense minister. Obama's presence in the Greek capital, for two days, is a working visit, not an official visit. 

Athens under a massive security blanket, as roads where the US presidential limousine may pass will be closed to traffic. Five metro stations will be closed as well. 

Large convoy of vehicles, including two similar Cadillac limousines, one of which is carrying Barack Obama, depart the airport at 10:50 (08:50 GMT), east of Athens proper, for the undisclosed location where the US president will be hosted. His program commences in roughly two hours, first being received by the Greek President, and then by Greek Prime Minister Alexis Tsipras.

"New Democracy welcomes US President Barack Obama expecting a productive and
useful visit for the Greek interests," said main opposition party in an
announcement on Tuesday.

The relations of mutual cooperation with the US are a stable choice of our
national strategy," added ND noting that "New Democracy did not discover America
today but it follows a policy based on the over time national interests and the
country's strategic orientation."

US President Barack Obama arrives at the Greek Presidential Palace.

Barack Obama received at the presidential mansion in central Athens by Greek President Prokopis Pavlopoulos, expresses satisfaction over his visit to Greece. Refers to significance of visiting the land where democracy began, ideas that inspired the creation of the United States.  

Obama: Congratulates Greece over its handling of the refugee issue, emphasizes that no country should deal with such a problem alone.

Obama praises the European Union. Says he brings a message of encouraging growth and giving young people around the world with ideas the same opportunities as the rest of the world. 

Obama reminds that Greece has faced numerous challenges over recent years, with the Greek people passing through difficult times. Refers to the start of a better period; says US will work to continue this course. More work to be done.

US President Barack Obama praised Greece for what he called the country's “humanitarian and compassionate manner” in dealing with the unprecedented, by post-war standards, Mideast war refugee issue. His comments came during his meeting with Greek President Prokopis Pavlopoulos on Tuesday.

Obama began a two-day working visit Athens that is loaded with symbolism, given that it is his first to the country -- which dominated international headlines over the past few years -- and part of his last overseas tour as US president.

In reference to the landmark Lausanne Treaty, which finalized borders of the new Turkish state in 1923 and solved many of the Near East issues at the time, Pavlopoulos said this was 'inconceivable' and would undermine not just Greek borders but EU borders.

Obama received at the Maximos Mansion by Greek Prime Minister Alexis Tsipras.

Greek prime minister's office, in a neo-classical 19th mansion, is separate by a side road from the presidential mansion, with a park separating the two official buildings from Parliament. The entire area has been closed to traffic and pedestrians.

Obama-Tsipras press conference begins

Tsipras: Thanked Obama again for choosing Athens as one of his destinations on his last trip as US president; says two Obama terms changed America; refers to Bill Clinton visit in 1999 and latter’s acknowledgement of US mistakes vis-à-vis junta that ruled Greece between 1967-74.

Tsipras: Obama choose different path for America when economic crisis hit in 2008, compares with what he calls European leadership's insistence on austerity, which causes incalculable social and political problems.

Tsipras: Greece returning slowly to normalcy; acknowledges moral and practical assistance by Washington to Greek government during difficult summer of 2015

Tsipras: Greece, US acquiesced to debt relief for Germany in 1953, in post war period; Germany today, Europe's economic engine, should now do the same for Greece; problems exacerbated for Greece due to austerity, one-fourth of GDP lost

Tsipras: We'll continue to promote reforms that promote growth; what interest us more is for results to unburden weaker strata of society, particularly the younger generations; after seven years we cannot tolerate more austerity; debt relief, lower primary budget surplus targets after 2018 and inclusion in QE program is deserved by the country.

Tsipras: Today we discussed several crucial issues: boosting bilateral cooperation, US investments in Greece; discussed energy projects / pipelines underway; Greece's human resources potential; Greek-American community

Tsipras: Discussed cooperation in refugee crisis, regional security amid an increasingly insecure region; Greece a foundation for stability, peace in the region, acting always within international law; a barrier to terrorism; a country that offered shelter to hundreds of thousands of refugees

Tsipras: Underlined the importance of bilateral ties with Turkey, but based only on mutual respect, without threats of war, violence; discussed viable solution for Cyprus, which is an EU state; discussed bi-communal talks for a Cyprus solution, which bring hope but also feature open issues; solution must benefit all people on Cyprus; withdrawal of Turkish troops necessary.

Obama: Refers to extent of economic crisis on Greece and its effects on its people

Obama: Discussed with Greek PM the steps his government will take to end crisis and boost economy; again said austerity only not a solution
