The United States embassy in Baghdad was bombarded with three rockets that triggered the anti-aircraft system, avoiding great damage.
The authorities have not yet reported whether there were victims or material damage, although the staff was moved to safer places.
On January 5th, five Grad rockets hit the US base in Ain al-Assad, Al-Anbar province, while a convoy in transit to support US soldiers in Babel was stopped by a roadside explosive device.
Attacks took place previously on a road between Muthana and the south of the country against two other logistical convoys belonging to the Pentagon-led international alliance.
Similarly, Al-Mayadeen informed the launch of four Katyusha projectiles, which hit a US facility located in the vicinity of the Baghdad international airport.
The United States and Iraq signed an agreement last July to withdraw US combat troops, which was fulfilled on December 31st, but the consent stipulated that some 2,500 US soldiers and a thousand from NATO would remain in Iraq as advisers and trainers.
The Iraqi Resistance, however, does not make distinction between combat forces and advisers, according to statements by their leaders, who consider they are all occupying forces that must leave the country, be it the easy way or a hard way.
