United States President Biden has confirmed that there is a virtual summit scheduled with G7 leaders, to discuss the ongoing crisis in Afghanistan, after a call with U.K. Prime Minister Boris Johnson.

"They agreed to hold a virtual G7 leaders' meeting next week to discuss a common strategy and approach," the White House said in a statement.

This was the first call between Biden and a foreign leader since the Taliban took over Kabul on Sunday night. Since Sunday, the United States have been rapidly and hastily evacuating final US and allied personnel from Kabul's airport.

The Taliban victory has sparked fear and chaos in the city, with Afghan citizens also trying to flee the country, and the numbers are causing foreign leaders to worry about a humanitarian crisis. Biden has been criticised for the lack of preparation in evacuating thousands of people from the country.

The U.S. President and Mr. Johnson "discussed the need for continued close coordination among allies and democratic partners on Afghanistan policy going forward," the statement said, including "ways the global community can provide further humanitarian assistance and support for refugees and other vulnerable Afghans."

Additionally, a Downing Street spokesperson said the two leaders welcomed US-British cooperation in the ongoing evacuation effort.

"They resolved to continue working closely together on this in the days and weeks ahead to allow as many people as possible to leave the country," a statement said. Johnson reportedly also stressed "the importance of not losing the gains made in Afghanistan over the last twenty years."

"The prime minister and President Biden agreed on the need for the global community to come together to prevent a humanitarian crisis," the statement said.

The G7 committee comprises Britain, The United States, Canada, Italy, Germany, France and Japan, and will be headed by Britain this year.

The G7 are not the only organisation to have convened an emergency meeting in the wake of the crisis. The United Nations human rights council will also meet on August 24th to address the "serious human rights concerns" following the Taliban takeover.

The meeting is being held after an official request from the representatives of Pakistan, who act as coordinator of the Organisation of Islamic Cooperation, and Afghanistan. The joint request has been supported by 89 countries thus far.

Meanwhile, the United Arab Emirates has confirmed that the country has Afghanistan's former President, Ashraf Ghani and his family into the country "on humanitarian grounds". The former President fled Afghanistan on Sunday during the takeover, to avoid bloodshed. His whereabouts were unknown until today.

Tens of thousands of people have attempted to flee Afghanistan, to escape the hardline Islamist rule expected under the Taliban, or fearing direct retribution for siding with the US-backed government that ruled for the past two decades.
