Smiles are everywhere and the atmosphere crackles with excitement as Pakistanis across the country celebrate their nation's 71st anniversary of independence.

Major cities have been decked out in bright, colourful lights, creating a cheery and festive atmosphere.

The festivities officially kicked off last night, with charged youngsters racing through streets on bikes, armed with various patriotic paraphernalia ranging from the ordinary ─ flags and green and white clothing ─ to the novel ─ noisy vuvuzelas.

The day dawned with the usual official functions and ceremonies ─ a 31-gun salute in the capital and 21-gun salutes in the provincial capitals, as well as a major event in Islamabad in which top government functionaries and armed forces' officials took part.

Schools and colleges also organised functions for students, and a rally was held in the capital to mark Independence Day.

Border security forces ─ both on the Indian side at Wagah, and the Afghan side at Torkham ─ exchanged sweets and greetings with each other as a gesture of goodwill.

President Mamnoon Hussain and caretaker PM Nasirul Mulk issued separate messages addressing the nation on Aug 14.
