Japanese nongovernmental organizations and Diet members expressed serious concern Tuesday over the conflict-ravaged Gaza Strip, urging the government and the international community to be more proactive in working toward peace in the Middle East.

The event, cohosted by several human rights groups, including Amnesty International Japan and Human Rights Now, was held while Palestinian President Mahmoud Abbas was in Japan for meetings with Prime Minister Yukio Hatoyama and Foreign Minister Katsuya Okada.

Kazuko Ito, secretary general of Human Rights Now, stressed that the International Human Rights Law may have been violated during fighting in the Gaza Strip between December 2008 and January 2009. According to the organizers, the conflict ended in the death of about 1,400 people, of whom only 13 were Israelis.
