Kulkul made the denial in an interview with the News Agency of Nigeria in Kano on Thursday.
He said the speculations were totally untrue as the market would open on Thursdayfor usual business activities.
He said: “The market is not closed.
“Only the affected section of the market was closed by security agents to enable them carry out investigations.
“More so, the Emir of Kano, Alhaji Muhammad Sanusi II and Governor Rabi’u Kwankwaso are expected to visit the scene of the incident.
“That is why that area is closed.”
Kulkul urged customers visiting the market from within and outside the country to ignore the rumour as the market would continue to operate.
The chairman also assured that the union and security agencies were collaborating to provide adequate security in the market.
Two female suicide bombers had on Wednesday detonated explosives at Ibrahim Taiwo Way, near the market, killing themselves and four others.
