In a July 16 interview with Qatar’s Al-Jazeera TV network, Sheikh Kamal Khatib, the deputy head of the Islamic Movement in Israel, said that Israel has been injecting chemical substances into the walls of the Al-Aqsa Mosque in order to cause its corrosion. Sheikh Khatib explained that these substances have a delayed effect, enabling Israel to claim that the cracks and fissures in the mosque structure are the working of nature.
Kamal Khatib: 22 years ago, we said that the Al-Aqsa Mosque was in danger. At the time, we said that throughout the excavations, the occupation used chemical substances that have a long-term effect. These substances could eat away at the rocks and pillars, but its effect would not show immediately, and afterwards they would be able to claim that the cracks in Al-Aqsa [walls]... It has happened. There are fissures and sinkholes in some places. [Their plan was that] they would be able to claim that it was the working of nature. It seems... Actually, I shouldn't say "seems"...
Interviewer: Sorry to interrupt you, Sheikh, but did [Israel] do it now, when the mosque was closed? Did it execute this secret scheme?
Kamal Khatib: Yes, yes, yes, yes, yes. I fear - I am almost convinced - that the goal of Israel in closing the mosque was not just to search for weapons, as the [Israelis] claimed. They know that there are no weapons inside the blessed Al-Aqsa Mosque.
