LAHORE: Several thousand supporters of the Pakistan Tehreek-i-Insaf (PTI) from different parts of the country reached Adda Plot on Raiwind Road on Thursday to participate in the `accountability movement` seen by many as a `door-die` act of Imran Khan.

Caravans of supporters started pouring in the city a day ahead of a march on Raiwind being organised by the PTI to pressure Prime Minister Nawaz Sharif and his family to explain their position over `proof of their corruption` published in the Panama Papers some six months ago.

A stage was being erected and seating arrangements were being made till late night in Adda Plot close to the prime minister`s Jati Umra residence.

Mass gathering started picking up momentum late in the evening as the PTI leaders, including its chairman Imran Khan, led rallies from different parts of Lahore and Raiwind to the protest venue.

Mr Khan is already in an aggressive mood and has announced that he will send a strong messagetoMrSharifaswellasIndianPrimeMinisterNarendra Modi in the wake of skirmishes along the Line of Control.

Mr Khan says he has exhausted all forums, including peaceful protests, and hinted that he may move his party to second stage of an `aggressive agitation` to compel the prime minister and his family to explain how they have set up of fshore companies and stashed huge money and bought expensive flats abroad.

Talking to journalists, he said his party had planned the march to send a message to Mr Sharif but now, in the backdrop of alleged Indian `surgical strikes`, it would also send a strong message to the Indian premier. `I will effectively respond to Narendra Modi which Nawaz Sharif has so far failed to do.

In the wake of alerts that Indian spy agency Research and Analysis Wing and its Afghan counterpart had planned terrorist activities to target the PTI march, Mr Khan sounded undeterred, saying such threats had always been conveyed whenever the party planned to raise voice against the rulers` corruption and rigging in 2013 general elections.

He said the government was afraid of the PTI and employing `mean tactics` to deter people from participating in the march.

But, he added, the nation was united and would express unity by joining him at the Raiwind march in a bid to `oust the corrupt mafia` from the corridors of power.
