UNITED NATIONS (AP) - Iraq has informed the United Nations that the Islamic State extremist group has taken control of a vast former chemical weapons facility northwest of Baghdad where 2,500 chemical rockets filled with the deadly nerve agent sarin or their remnants were stored along with other chemical warfare agents. <br />
Iraq's U.N. Ambassador Mohamed Ali Alhakim said in a letter to U.N. Secretary-General Ban Ki-moon circulated Tuesday that ``terrorist'' groups entered the Muthanna site June 11 and seized weapons and equipment from the protection force guarding the facility. <br />
He singled out the capture of bunkers 13 and 41 in the sprawling complex, which according to a 2004 U.N. report also contained the toxic agent sodium cyanide, which is a precursor for the chemical warfare agent tabun, and artillery shells contaminated with mustard gas.
