Billboards and banners felicitating Pakistan on its 72nd independence day have been put up across Tehran, the capital of Iran, Radio Pakistan reported on Tuesday.

The text in Persian on the billboards, photos of which are available with Dawn.com, congratulates Pakistan on its independence anniversary and depict historical landmarks from the four provinces. The hoardings have been put on highways and bridges across the Iranian city.

According to Radio Pakistan, Iran's supreme leader Ayatollah Ali Khamenei has also felicitated the Pakistani nation on the occasion.

Pakistan's relations with Iran appear to be on an upward trajectory. In a call to prime minister-in-waiting Imran Khan, Iran's President Hassan Rouhani had said that his country's relations with Pakistan are not only that of a neighbour but go deeper as the two countries share the same religious and cultural values.

"We want to develop special trade relations with Iran," Khan had told Rouhani in response, adding that Pakistan wishes to see further improvement in relations on the diplomatic level.

The Iranian president had also extended an invitation to Khan to visit Iran after taking the oath, which was accepted by the Pakistan Tehreek-i-Insaf chief.

Last month, the two countries pledged to further deepen their military cooperation.
