Sunni Islamist militants seized the Qaim border crossing between Iraq and Syria Saturday after a daylong battle in which 30 Iraqi soldiers were killed, security officials reported in Baghdad. The jihadists, fighting to establish an Islamist state spanning Iraq and Syria, can now more easily transfer weapons and heavy equipment between their two battlefields. Iraqi Prime Minister Nouri al-Maliki, after losing major cities and Sunni regions to the Sunni radicals’ offensive, faces rising demands to form a more inclusive government or step aside.
