An explosion rocked Palestinian national security headquarters in the Gazan town of Jabaliya on Tuesday, killing at least two people and wounding several others, Palestinian security officials said. Palestinian sources added that the blast appeared to have been caused by an Israeli artillery shell.
The blast led to the collapse of a one-floor building inside the compound.
The Israeli army denied any involvement in the explosion, but it should be mentioned it has been constantly shelling areas in Gaza Strip.
