The injection of cash, which comes as the Taliban steps up its annual summer offensive launched in late April, has helped Pakistan's foreign exchange reserves reach a fresh high of about USD 19 billion, state bank officials said.
Regular payments to Pakistan under the Coalition Support Fund (CSF) programme began in 2001 when Pakistan joined the US-led coalition in Afghanistan as a "frontline ally".
Pakistan provides use of its air bases and other facilities in exchange for the reimbursements.
Pakistan has received a total of USD 13 billion in CSF payments since the programme began.
