Security measures were strengthened in Istanbul following the most recent deadly attack in France. Police surrounded the French Consulate on Istanbul's İstiklal Avenue in Taksim in the wake of an attack in which a semi-truck smashed into a crowd during Bastill Day celebrations late on Thursday. A group of armed special operations police in camouflage have begun to patrol the busy İstiklal Avenue after the announcement. Security was strengthened yesterday at Atatürk International Airport as well.

Istanbul was already on alert after the French Embassy in Ankara and the French Consulate in Istanbul were closed after the country's diplomatic missions in Turkey cancelled their planned events to mark France's national Bastille Day due to security concerns, on July 13.

"Information points to a serious threat against plans for the celebration of the July 14 national holiday in Turkey. As a precaution, we have decided, in conjunction with the Turkish authorities, to cancel the celebrations," a statement from the mission in Istanbul said.
