Police and protesters have again clashed in Istanbul as massive crowds gathered for a sixth successive night to demand the release of the city’s mayor, Ekrem İmamoğlu, Turkey’s main opposition presidential candidate. He was arrested last week and charged with corruption. Orla Guerin is in Istanbul.

It was another mass demonstration here tonight, another night of defying the government ban on protests. There was a very large security presence. We saw a lot of riot police with their shields at the ready. We certainly saw and felt the impact of tear gas being fired and in fact it is still here now in the air. And the water cannon that were brought here tonight were not used in this location, but we know that they were used in the capital, Ankara.

The White House has confirmed that a prominent journalist was accidentally texted classified military information. A spokesman said the administration was reviewing how Jeffrey Goldberg of “The Atlantic” magazine had received classified military plans for U.S. strikes on Houthi rebels in Yemen via the Signal messaging app.

The U.S. Senate Minority Leader Chuck Schumer called for a full investigation into the leak.

“This is one of the most stunning breaches of military intelligence I have read about in a very, very long time. What we have here are senior U.S. leaders, including the vice president and secretary of defense, having classified discussions of military action over an unsecure app.”

An appeals court judge in Washington has strongly criticized the Trump administration for its summary deportation of alleged Venezuelan gang members to El Salvador 10 days ago. James Boasberg said that Nazis had got better treatment in World War II.

His comments came as government lawyers tried to overturn a restraining order that has stopped the deportations.

Argentina’s President Javier Millet has announced he will declassify all intelligence files relating to the period when the country was under military rule. The announcement was made on the anniversary of the military coup. Our America’s regional editor, Leonardo Rocha, reports.

Thirty thousand people are estimated to have been killed by the military authorities between 1976 and 1983 when democracy was restored.

Mr. Millet said he wanted Argentines to get a full picture of what happened during that period, including murders committed by left-wing guerrillas that were active throughout the 1970s. He said that current narrative was controlled by the left.

Human rights campaigners and the opposition have welcomed the decision, but many fear most of the documents incriminating the military and the secret services have already been destroyed.

The files will begin to be released on Monday.
