Turkey has warned its citizens against travel to the United States, saying Turks face the risk of arbitrary arrest and should take precautions if they do decide to travel.
The move came after the USA announced a new travel advisory on Wednesday and named Turkey as a country with an "increased security risk" along with Sudan, Pakistan and Guatemala.
"Ankara is as safe as Washington, Istanbul is as safe as New York", Yildirim said.
Ankara reacted furiously to last week's conviction in NY of Turkish banker Mehmet Hakan Atilla on charges of violating sanctions against Iran.
The travel warning came days after the United States urged its citizens to reconsider travel to Turkey, citing terror threats and arbitrary detentions under an ongoing state of emergency.
A statement on Friday cited risks of "terrorist" attacks as well as arbitrary arrests in Turkey's Western ally.
The two countries have also fallen out over the US's refusal to extradite US-based cleric Fethullah Gulen, who Turkey holds responsible for the 2016 coup attempt, and U.S. military support for Kurdish rebels in Syria which Ankara considers a terrorist group.
Turkey is also angered at USA support for Syrian Kurdish militia that it considers to be "terrorists".
The U.S. a year ago temporarily suspended visa services to Turkish citizens following the arrest of a local Turkish employee of the U.S. Consulate in Istanbul.
