After US President Donald Trump's diatribe against Pakistan, the head of the Central Intelligence Agency (CIA) has now launched a barrage of allegations, accusing Pakistan of providing safe havens to terrorists.

Speaking to CBS news on Monday, CIA chief Mike Pompeo reiterated his Trump's allegations, threatening Islamabad that they would 'protect' the United States if Pakistan fails to address the issue.

"We see that Pakistan is continuing to provide safe harbor havens inside of Pakistan for terrorists who present risks to the United States of America," Pompeo told US media.

"We are doing our best to inform the Pakistanis that that is no longer going to be acceptable."

The statement comes amid a period of heightened tensions between the two nations that followed a similar statement from President Donald Trump.

The US president accused Pakistan of giving nothing but lies and deceit, thinking US leaders to be fools.

"They give safe havens to the terrorists we hunt in Afghanistan, with little help. No more!" Trump said in his tweet last week.

Pompeo said: "If they fix this problem, we're happy to continue to engage with them and be their partner. But if they don't, we're going to protect America.

The statements by top US officials have drawn a strong reaction from Islamabad, with the summoning of the US ambassador to its Foreign Office in a rare public rebuke.

Last week, Foreign Minister Khawaja Asif slammed that the "US behaviour is neither that of an ally nor of a friend."

"It is a friend who always betrays," he said on Thursday, raising questions over United States' motives in the region.

"They, the US and allies, have the best and highly equipped forces. How come they could not perform in Afghanistan," he questioned, noting that Pakistan fought a war with its own resources and it succeeded in Swat, Bajaur, North Waziristan and other areas.
