Afghanistan President Ashraf Ghani’s scheduled trip to the US has been postponed, according to officials on Saturday.

Earlier, it was reported that Ghani, along with a 13-member delegation would embark on the trip on Saturday and he would meet his US counterpart Donald Trump on September 9.

However, the reason for the postponement was not known, Khaama Press reported.

The development emerged after the US envoy negotiating with the Taliban, Zalmay Khalilzad, briefed Afghan officials in Kabul on an agreement “in principle” the two sides had reached following nine rounds of talks in Qatar.

On Wednesday, Presidential spokesperson Sediq Sediqqi said that the Afghan government had concerns regarding the consequences and dangers of the peace agreement, similar as the former American officials and senators have raised their concerns in this regard.

Earlier on Thursday, US Special Representative for Afghanistan Reconciliation, Zalmay Khalilzad abruptly returned to the Qatari capital, Doha, for more talks with the militant group, TOLO News reported.

The Taliban has so far rejected negotiations with the Afghan government, seeing it as a puppet of the United States.

While US and Taliban negotiators appeared to be closing in on an accord to end the fighting, the militant group has been stepping up operations across Afghanistan in recent days.

On Friday, the Taliban launched an offensive against the western Afghan city of Farah — the third provincial capital to come under attack in less than a week.
