Nasser Al-Hadmi is the head of the Jerusalem Committee against Demolition and Displacement.
He is also apparently a member of Hamas.
He is in Palestinian media today warning about plans by "Jewish settler groups" to "storm" the Temple Mount during the Passover season.
Al Resalah says, "The Jewish settlement associations are working to mobilize their members for a major attack on the blessed Al-Aqsa Mosque in the coming month of Ramadan, which coincides with the holidays for the Jews."
He is counting Shabbat Hagadol which is Sabbath before Passover, the fast of the first born which is the day before Passover, the entire holiday of Passover itself, Yom HaAliya and Yom HaShoah, all of which occur during the Hebrew month of Nisan, which coincides this year with Ramadan.
Israel often has to juggle access to holy places where Jewish and Muslim holidays coincide, but the haters are trying to use this year's coinciding calendars as excuses for violence and a repeat of last year's Hamas rocket attacks on Jerusalem.
Nasser al-Hamdi wants a pre-emptive "explosion" to pressure Israel to take away Jewish rights in Jerusalem, saying, "Unless things explode in the coming Ramadan, the occupation will impose a new reality, permanent prayers for settlers inside Al-Aqsa, and setting times for Jews to pray in the mosque, especially in Bab Al-Rahma."
This is as explicit incitement to violence as can be.
Last year, Israel temporarily expelled al-Hamdi and three other Hamas activists from Jerusalem in order to keep the calm. He might still be under that ban. Given that he has made clear his desire to start an explosion in Jerusalem this April, they might need to do more in order to keep things calm.
