Semarang (Central Java) – Dozens of students protested against the humanitarian aid group attack, demanding the UN Security Council stop Israeli aggression.

They brandished posters with slogans such as, "Jews Go to Hell", "Safe Palestine, Israel Uncivilized."

The posters referred to the Israel attack of the Mavi Marmara ship, which was on its way to blockaded Gaza with freight of humanitarian aid.

As many as 16 activists were killed during the raid. Dozens, including one of 12 Indonesian volunteers, were injured.

Rally coordinator Ibnu Dwi Cahyo said the attack was by no means justifiable. "We condemn the incident. The Indonesian government should urge the UN to stop Israeli arrogance," he said.
