A German army officer trying to help at-risk Afghans flee their country launched a blistering rhetorical attack on Germany's evacuation efforts on Tuesday.

Cpt. Marcus Grotian told reporters in Berlin that he was "overwhelmed by disbelief at the way Germany's governing parties and politicians disregarded warnings" about the Taliban advance and accused Chancellor Angela Merkel's office of failing to step in when needed.

Grotian, who heads a network of volunteers trying to help locals who worked for German institutions in Afghanistan, said some 6,000 Afghans are still waiting to be evacuated and many likely won't make it.

"There will be many, too many human tragedies to come. That's absolutely clear," he said.

Grotian accused German officials of creating a dysfunctional bureaucracy that is making incomprehensible decisions about who can board evacuation flights and who can't.

He said the mixed messages being sent to Afghans by German bureaucrats would likely mean some will miss other opportunities to leave the country because they are still waiting for Germany to evacuate them.

"Everyone who has worked for Germans must now be let through, because there won't be many more chances," said Grotian. "They've been rejected three times, some of them four. There may not be a fifth when the planes don't fly anymore."

The Dutch military has completed twelve flights using military transport planes out of Kabul to air bases in the region since the Taliban seized control of Afghanistan.

Seven flights carrying more than 1,000 people evacuated from Afghanistan have arrived in the Netherlands since the Taliban seized control of the country.

The flights have carried Dutch nationals, Afghans and citizens of other countries.

On Tuesday, the government agency that houses asylum seekers opened a third center for Afghan evacuees at a military base in the central town of Ede.

Foreign Minister Mevlut Cavusoglu says Turkey has so far evacuated 1,404 people from Afghanistan — 1,061 of them Turkish nationals and 343 nationals of “various countries.”

“Because of our (troops’) presence at the airport, many countries, international organizations or NGOs have asked our help in evacuating their personnel,” Cavusoglu told reporters Tuesday. “We have been providing assistance to them together with the United States and Britain.”

Cavusoglu said that there were some 4,500 Turkish nationals in Afghanistan but only around 200 are still waiting to be evacuated.

“We have contacted each one of them. ... An important number of them said they did not want to return,” Cavusoglu said, explaining that they included people who had businesses or jobs in Afghanistan or were married to Afghans.

“We of course, respect their decision but we have also made the necessary suggestions and warnings,” he said.

A week after leaving Kabul and arriving in Ukraine, prominent Afghan film director Sahraa Karimi on Monday urged world leaders not to recognize the Taliban's authority in Afghanistan.

Karimi, the head of the national cinema body Afghan Film, managed to escape Afghanistan's capital on August 15 when Taliban forces seized the city and taking control of most of the country.

The 38-year-old graduate of the Slovak Film and Television Academy asked the Academy to help her and her family to leave the country.

With the help of the Ukrainian government, she was able to board a Turkish plane and eventually arrive in Ukraine.

Speaking at the Kyiv Summit of First Ladies and Gentlemen, organized by Ukrainian First Lady Olena Zelenska on the sidelines of the Crimea Platform, Karimi called on international leaders "not to stay silent".

"I beg you, please, tell your husbands not to give them recognition," she said while sobbing on the stage.

"If they give the Taliban political recognition, if they accept them, then they will destroy our lives, women's lives," Karimi added.

The U.N. human rights chief warned Tuesday that she had credible reports of "summary executions" and restrictions on women in areas under Taliban control in Afghanistan.

China says the international community should support chances for positive developments in Afghanistan rather than impose sanctions on the Taliban.

“The international community should encourage and promote the development of the situation in Afghanistan in a positive direction, support peaceful reconstruction, improve the well-being of the people and enhance its capacity for independent development,” Foreign Ministry spokesperson Wang Wenbin told reporters at a daily briefing on Tuesday.

“Imposing sanctions and pressure at every turn cannot solve the problem and will only be counterproductive,” Wang said.

China, which shares a narrow border with Afghanistan, has seized on the ugly scenes at Kabul airport to redouble its harsh criticism of US actions in the country, particularly its attempt to install a Western-style democracy. Beijing has kept open its embassy in Kabul and sought to maintain friendly relations with the Taliban.

Prominent Afghan women's rights activist Zarifa Ghafari arrived in Germany late Monday after fleeing to Pakistan from Afghanistan last week.

Armin Laschet, the governor of Germany’s North Rhine-Westphalia state and leader of the Christian Democratic Union met Ghafari and said it was important to help as many women as possible to leave Afghanistan in the coming days.

Britain says it has evacuated 8,600 U.K. citizens and Afghans from Kabul in recent days, 2,000 of them in the last 24 hours.

But Defense Secretary Ben Wallace conceded that “we’re not going to get everybody out of the country” before the U.S.-led mission ends on Aug. 31.

Britain and other allies are pressing President Joe Biden to extend the evacuation past the end-of-the-month date agreed with the Taliban. But Wallace told Sky News it’s unlikely Biden will agree.

The government said one of the evacuees on a British plane turned out to be a person on a U.K. no-fly list. Wallace said the individual was identified on arrival in Britain was investigated and judged “not a person of interest” to security services.
