The Kurdish militant group TAK says it carried out Sunday's deadly attack in the Turkish capital, Ankara in revenge for 'military operations in the mainly Kurdish south-east'.

Turkish President Recep Tayyip Erdogan has vowed to bring terrorism "to its knees" after an attack in the capital Ankara that killed at least 34 people.

At least 28 people are killed and 61 wounded Wednesday by a car bomb targeting the Turkish military in the heart of the capital Ankara, the latest in a string of attacks to shake the country.
