World leaders arrive for G20 Summit in Turkey

Modi tweeted that he would 'meet world leaders and discuss global economic and security issues'

With Paris attacks clouding the G20 Summit, US President Barack Obama and UN Secretary General Ban Ki-moon today arrived in this Turkish coastal town to join other world leaders including Prime Minister Narendra Modi for the meeting that would be dominated by talks on terror.

Modi, who reached here late last night from London after his three-day visit to the UK, tweeted he would "meet world leaders and discuss global economic and security issues".

The official economic agenda is likely to be overshadowed by a series of intense meetings the world leaders will hold on the margins of the Summit on the Syrian civil war, the refugee crisis in Europe, the Paris attacks and the growing threat of the terror group ISIS.

European Commission President Jean-Claude Juncker, IMF Managing Director Christine Lagarde and World Bank President Jim Yong Kim arrived here last night.

Also to arrive yesterday were Chinese President Xi Jinping, Indonesian President Joko Widodo, Prime Minister of Spain Mariano Rajoy, Korean President Park Geun-hye, Japanese Prime Minister Shinzo Abe and Mexican President Enrique Pena Nieto.

Canadian Prime Minister Justin Trudeau, Prime Minister of Singapore Lee Hsien Loong, Australian Prime Minister Malcolm Turnbull, South African President Jacob Zuma and Brazilian President Dilma Rousseff also arrived yesterday.
