President Erdoğan supports 'Hello Brother' campaign

President Recep Tayyip Erdoğan on Saturday joined the "Hello Brother" social media campaign, which refers to the final words of the first victim in New Zealand mosque attacks.

Terror victim Haji Daoud Nabi, 71-year-old Afghan national, said "Hello Brother" to the gunman -- who massacred dozens of innocent Muslims in al-Noor Mosque -- moments before being shot dead at the entrance of the mosque.

President Erdoğan shared a video on his Twitter account with #HelloBrother and greeted Nabi, who became a symbol of innocence on social media.

Erdoğan also retweeted videos shared by prominent Turkish football teams and the country's English-language broadcaster TRT World to support the campaign.

At least 50 Muslims were killed and as many injured on March 15 when a terrorist -- identified as Australian-born Brenton Tarrant, 28 -- entered the Al Noor and Linwood mosques in Christchurch and shot worshippers in cold blood, including four children younger than 18.

The terror suspect has been charged for the massacre and is being held at a maximum-security prison in Auckland.
