March 29 (UPI) -- Iran's parliament speaker, Mohammad Bagher Ghalibaf, issued a warning Saturday against a possible ground troop invasion as the U.S. military sends more troops to the region.

Ghalibaf made the comments in a message marking 30 days since the start of the war. The United States and Israel began strikes on Iran on Feb. 28 in their efforts to diminish the country's nuclear weapons program.

Ghalibaf accused the United States of secretly planning a ground invasion of Iran. On Saturday, two U.S. ships arrived in the region carrying 3,500 U.S. service members as well as fighter jets, transport aircraft, amphibious assault vessels and other tactical assets. More troops were expected, U.S. Central Command said.

"The enemy publicly sends messages of negotiation while secretly planning a ground invasion -- unaware that our men are waiting for American troops to enter on the ground, ready to unleash devastation upon them and punish their regional allies," Ghalibaf said, as reported by CNN.
