US President Donald Trump’s decision to recognize Jerusalem as the capital of Israel is an “irreparable mistake,” said Abdul Rab Rasul Sayyaf, Head of the Council for Protection and Stability in Afghanistan (CPSA), addressing a gathering in Kabul on Thursday. 

His comments come a day after Trump announced that he officially recognizes Jerusalem as the capital of Israel.  

Trump described the decision as "a long overdue step" to advance the Middle East peace process.

The US leader said his country would support a two-state solution if approved by both the Israelis and the Palestinians.

“Israel is a sovereign nation with the right, like every other sovereign nation, to determine its own capital,” Trump said.

Ahead of the decision, a spokesman for Palestinian President Mahmoud Abbas warned it will have "dangerous consequences" for the region.

At the gathering, Sayyaf criticized government over the current problems within the administration, including the challenges faced by the electoral bodies.

He called on the National Unity Government’s leaders to maintain the system and to “prevent destroying it”.

"We are not happy with the government and we are tired of its monopoly, but we have never wanted the system to fall. The Government is not listening to us, but we do not want to create any problems for the nation," Sayyaf said.

He said the situation shows that government is not intending to hold the due elections. “Preparations have not been made for elections. Afghanistan will face a crisis if the elections are not held,” he warned.

Sayyaf also criticized the government for what he called the sidelining of mujahedeen.

"No one must say that extremists were brought to Afghanistan by mujahedeen and then were used against Russia; the extremists emerged after mujahedeen," Sayyaf said.
