Countries offering support for attack on Iraq

More than 20 countries have offered logistical help ranging from airspace to troops for a possible US-led war against Iraq.

Following is a snapshot of the likely roles different nations could play in a war on Iraq:

Albania - Offered to send troops in a largely symbolic gesture.

Australia - Sent 2,000-strong force of elite SAS troops, fighter jets and warships to the Gulf.

Bahrain - Headquarters of the US Fifth Fleet.

Britain - Washington's chief ally on Iraq has sent or committed 45,000 military personnel, planes and warships.

Bulgaria - Offered use of airspace, base and refuelling for US warplanes; sent non-combat troops specialising in chemical and biological warfare decontamination.

Croatia - Airspace and airports open to civilian transport planes from the coalition.

Czech Republic - Sent non-combat troops specialising in chemical warfare decontamination in response to US request.

Denmark - The government decided to take part in the military action with a submarine and a corvette and a medical team.

Germany - Despite opposition to a war on Iraq, Germany has chemical warfare decontamination specialists in Kuwait which will be increased to between 200 and 250 troops.

Hungary - Hosts a US base where Iraqi exiles are trained for possible post-war administrative roles.

Italy - Offered logistical help and use of military bases and ports under longstanding Nato commitments. Parliament approved US use of Italian airspace and military bases, but no Italian troops will be involved.

Jordan - Opened its airspace to coalition planes; hosts US troops carrying out search and rescue operations in western Iraq and manning a Patriot anti-missile defence system.

Kuwait - Hosts coalition forces massed for an invasion.

Latvia - Government has decided to ask parliament to authorise the deployment of a small number of troops.

Oman - Base for US planes used in Afghanistan, but says will play no role in a war against Iraq.

Poland - To deploy up to 200 troops in the Gulf region, which will perform a non-combat role supporting any US-led offensive.

Portugal - Made available Nato air bases and an air base in the mid-Atlantic Azores islands.

Qatar - Hosts a mobile HQ for US Central Command; allowed Washington to expand an airfield to handle more combat jets.

Romania - Airspace and a base open to US warplanes; sent non-combat specialists in chemical decontamination, medics, engineers and military police in response to a US request.

Saudi Arabia - US and British planes use its Prince Sultan Air Base to enforce a "no-fly zone" over southern Iraq.

Slovakia - Sent non-combat troops specialising in chemical warfare decontamination in response to a US request.

Spain - Strongest ally of the United States and Britain. Promised use of its Nato bases for a strike on Iraq. Spain will send a medical support vessel equipped with nuclear, biological and chemical treatment facilities. A back-up frigate and 900 troops will accompany the support vessel .

Turkey - Parliament is likely to debate today opening its airspace to US warplanes but would not allow them access to airbases even for refuelling. It was not immediately clear what use the United States could make of its warplanes at the Incirlik airbase, already used by US and British jets to patrol a no-fly zone in northern Iraq.

UAE - Base for US surveillance aircraft and refuelling; host to an estimated 3,000 Western troops.

Ukraine - Agreed to US request that it send chemical warfare and nuclear decontamination experts.
