President Tayyip Erdogan on Monday said an attack on Turkey’s economy was no different from a strike against its flag or call to prayer, responding to a recent currency sell-off in religious and nationalist terms ahead of a major Muslim holiday.

In a pre-recorded address to mark the four-day Eid al-Adha festival, which starts on Tuesday, a defiant Erdogan said the aim of the currency crisis was to bring “Turkey and its people to their knees”.

The lira has tumbled some 40 percent this year, hit by worries about Erdogan’s influence over monetary policy and a worsening diplomatic rift with the United States. The sell-off has spread to other emerging market currencies and global stocks in recent weeks.

“The attack on our economy has absolutely no difference from attacks on our call to prayer and our flag. The goal is the same. The goal is to bring Turkey and the Turkish people to their knees, to take it prisoner,” Erdogan said in the televised address.

“Those who think they can make Turkey give in with the exchange rate will soon see that they are mistaken,” he said.

Erdogan stopped short of directly naming any countries or institutions, but he has, in the past, blamed the currency sell-off on a shadowy “interest rate lobby”, Western ratings agencies and financiers.

Amid the period of tense relations between Ankara and Washington, several gunshots were fired on Monday from a vehicle at the U.S. Embassy in the Turkish capital, causing no casualties. Reuters
