Two Irish nationals, one German, one Iranian, one Icelander, a UAE citizen and a person from Dubai were receiving treatment at several city hospitals, the health ministry said.

The German foreign office urged its citizens in Istanbul to stay indoors and check for updates on the situation. Just days before the blast, the German government had closed down its consulate and a school in Istanbul over intelligence about a possible terror attack.

There was no immediate claim of responsibility. Turkey has come under attack both from Islamist and Kurdish militants in recent months. The US consulate in Istanbul tweeted: "Saddened, shocked by explosion on Istiklal. We mourn with families of the lost, and we wish the injured a speedy recovery".

The attack could have seen a worse toll, as it struck the street around 11am local time when the area was still relatively quiet. With its many shops, cafes and restaurants, Istiklal Avenue is one of Istanbul's most famous landmarks and is normally crowded with people on Saturdays, but is at its busiest in the afternoon. Numerous countries have their consulate buildings in the area.

The Irish department of foreign affairs and trade updated its travel advice for Turkey with news of the attack. It called on its nationals planning to visit the country "to exercise caution".

The threat from terrorism in Turkey remains high," the advice read. "Vigilance is required in tourist areas such as Taksim Square in Istanbul and locations close to police stations, which may be targets for terrorist attacks."
