ISTANBUL — Turkey’s diplomatic row with Australia and New Zealand over the deadly shootings at two mosques in Christchurch worsened on Wednesday as Australia summoned the Turkish ambassador over President Recep Tayyip Erdogan’s remarks about the attack and New Zealand dispatched its foreign minister to confront him.

At campaign rallies this week, Erdogan has shown footage filmed by the Australian-born gunman who killed 50 worshippers at the Al Noor Mosque and the Linwood Islamic Center on March 15. Separately, the president warned on Monday that Turkey would fend off any hostile Antipodean visitors, “some in coffins,” like it did their forebears in World War I, if they threatened Turkey. On Wednesday, Erdogan’s spokesman said those comments were misconstrued.

Australia, which sends thousands of tourists each year to visit the battlefields on the Gallipoli peninsula in western Turkey, issued a travel advisory, warning its citizens to exercise caution in Turkey. Prime Minister Scott Morrison called Erdogan’s comments “reckless” and “vile” and told Ambassador Korhan Karakoc that if Erdogan didn't take back what he said, “all options were on the table.”

New Zealand Foreign Minister Winston Peters is traveling to Istanbul on Friday to attend a meeting of the Organisation of Islamic Co-operation in Istanbul, and Prime Minister Jacinda Arden said he would “set the record straight face to face” amid worries that Erdogan’s rhetoric could put New Zealanders in danger. Erdogan will speak at the meeting, but it was not clear whether he or his representatives would meet Peters.
