Clashes broke out at Istanbul's Sabiha Gokcen airport as well as at an airbase in central Turkey on Sunday, after plotters behind Friday's attempted coup in Turkey resisted arrest. An official said the situation was brought under control later and the officers had surrendered, Reuters reported

Security has been heightened in Istanbul since the attempted military coup late on Friday, July 15. Around 1,800 special forces police officers were deployed in the city from neighbouring regions, and President Recep Tayyip Erdogan has ordered F-16s fighter jets to patrol the country's airspace, Turkish state-run agency Anadolu reported.

Prime Minister Binali Yildirim said on Sunday that July 15 will be commemorated as "Democracy Fest Day" in Turkey, to mark the day the attempt at a military coup was foiled with the support of the country's people, Hurriyet Daily News reported. Yildiri, who had said earlier that those behind the incident will "pay a heavy price", praised the support extended by Opposition parties in the country.

The unrest that resulted from the attempted government overthrow has left 294 dead and more than 1,400 people injured, so far, The Associated Press reported. More than 6,000 arrests have been made in connection with the foiled coup, while 2,745 judges were fired across the country for suspected links with United States-based Islamic cleric Fethullah Gülen, whom Turkey believes was behind the attempted takeover and wants extradited from the US.
