The US government is cutting almost all security aid to Pakistan, saying it has failed to deal with terrorist networks operating on its soil.
The state department said the freeze would remain in place until Islamabad took action against the Haqqani network and the Afghan Taliban.
Earlier this week, President Trump accused Pakistan of lying and deceiving the US while receiving billions in aid.
The Pakistan government has forcefully pushed back against the US, a key ally.
After the earlier comments by Mr Trump it called attacks on it by US officials “incomprehensible” and said they “negated the decades of sacrifices made by the Pakistani nation”.
The US stance has been praised by India and Afghanistan, but China, which is investing tens of billions in Pakistan, has backed it.
