Iraq has signed contracts to buy weapons from Russia worth more than $4.2 billion recently, according to a Russian government document issued on Tuesday at a meeting between Prime Minister Dmitry Medvedev and Iraqi Prime Minister Nuri al-Maliki.

Russian President Vladimir Putin vocally opposed the US-led invasion of Iraq in 2003 but Moscow has since sought energy and arms deals with Baghdad and the contracts mean Iraq is now one of Russia's biggest weapons buyers.

The contracts were signed during visits to Russia by Iraq's acting defence chief in April, July and August, the document showed. It gave no further details.

The Russian daily newspaper Vedomosti reported late last month that contracts worth $4.3 million were being agreed ahead of Maliki's visit. It said they included deals for 30 Mi-28NE combat helicopters and 42 Pantsir-S1 mobile rocket launchers.

Russia delivered about $12 billion in weapons and signed about $3.7 billion in new arms contracts last year, according to Russian defence and security think-tank Cast. – Reuters
