Romania's Foreign Minister Mihai Razvan Ungureanu on Monday officially submitted his resignation to the office of Prime Minister Calin Popescu-Tariceanu, the government press office reported on Monday afternoon.
The resignation was sent to the office at noon and was registered, said Corina Vintan, spokesperson of the foreign ministry.
The prime minister on Friday asked Ungureanu to resign, on grounds of not informing the government about the detention of two Romanian workers in Iraq on Oct. 31, when they allegedly took pictures in a U.S. military base in the war-torn Middle Eastern country without permission.
Ungureanu announced on Sunday that he has decided to resign, but expressed his "difference of opinion" on the matter between him and his boss.
Ungureanu said he had met with Tariceanu and explained the reasons as to why he had failed to inform the government, adding that he was innocent.
The two Romanians had been working at the base for a U.S. contractor since May 2006. They were released last Friday, and will leave Iraq on Monday by a Romanian military plane.
They denied filming in the U.S. military base, but admitted to having infringed military rules, which their labor agreements required them to observe.
