Three Bangladeshi citizens, who were stranded in strife-torn Afghanistan, have returned home on Saturday.
They are among the six Bangladeshi BRAC staffers, who were awaiting return but were stranded because of the suspension of commercial flights from Kabul, the NGO said in a statement.
They left Kabul on August 22 and returned on Saturday via Kazakhstan.
The Turkish Airlines flight, which brought them, landed Dhaka around 5am, it added.
Around 3,000 staffers work across 10 provinces in Afghanistan. Of the 14 expatriate staffers working in Afghanistan, 12 were Bangladeshis, according to the BRAC statement.
As of Saturday, nine Bangladeshis have returned while another three are still stranded but safe in Kabul, it said before adding that efforts were underway to evacuate them as soon as possible.
BRAC has taken steps to ensure the highest security for its personnel in the face of growing violence in Afghanistan since the formal withdrawal of international troops began, said BRAC International Executive Director Shameran Abed.
"BRAC International has taken this decision with the utmost importance on the safety and security of its workers in Afghanistan," the statement quoted him.
