Iran warns U.S. of crossing its border

TEHRAN, Feb. 13 (UPI) -- A spokesman for the Iranian Foreign Ministry warned it would "give proper response" to any U.S. military operation that trailed suspected militants into Iran.

Iranian Foreign Ministry spokesman Seyed Mohammad Ali Hosseini said at a Wednesday news conference in Tehran that Iran would "give proper response to any move in this connection in a bid to defend its security and national sovereignty," the Fars News Agency said.

"Any entrance to the Iranian soil by any U.S. military force to trail suspects would be against international laws and could be pursued legally," he added.

A leaked 2005 U.S. intelligence document said U.S. military forces in Iraq could pursue members of the former Iraqi regime or suspected terrorists across the border into Iran or Syria.
