A long power failure across major Pakistani cities coupled with news that Pakistani President Pervez Musharraf was undergoing health check-up sparked rumours of a coup to unseat the President who is on an 18-day foreign tour connection with the release of his book 'In the Line of Fire'.
As power board officials appeared on TV channels to explain that the failure was due to a technical fault, Islamabad was abuzz with rumors that a Thailand-style coup has taken place.
General Musharraf meanwhile laughed off any threat to his power base when he was asked about the stability of his regime.
Power has since been restored in capital Islamabad after over a two-hour breakdown but most of the other cities in Pakistan reeled under power failure with hospitals and business houses switching over to generators.
The Pakistani President himself seized power in a military coup in October 1999.
