According to a report by Khaaasteh, the U.S. has allowed Iraq to pay Iran from funds frozen in banks in the country.
"Iraq has received waivers (from US administration) to release Iran's frozen assets and pay its debts. According to Iraq's trade bank, Iranian businessmen can now use Iran's blocked money to do their business, says Hosseini, the secretary of Iran-Iraq chamber of commerce," according to the report.
According to Iranian sources, Iraq owes Iran about $5-6 billion for use of electricity. Iran wants the debt to be paid in foreign currency, either dollars or euros.
