Rambam medical centre in Israel is constructing what it claims to be the world's largest underground emergency health centre in the northern port city of Haifa.
The facility is designed to withstand conventional, chemical or biological attacks and can be converted into a 2,000-bed hospital in case of a war.
The hospital is scheduled to be complete by May 2012. It will be able to produce its own electricity, and will have stores of oxygen, drinking water and medical supplies for about three days.
The facility is believed to be being built as a result of 2006 Lebanon War, during which Rambam medical centre came under rocket fire.
