Berlin (dpa) - The German parliament was Wednesday debating the country‘s military mission in Syria after the cabinet approved the deployment of up to 1,200 troops to support the international campaign to defeat Islamic State.The year-long, 134-million-euro (142-million-dollar) mission will not involve conducting airstrikes in Syria. Tornado fighter jets, a warship and aircraft for refueling combat jets will be deployed.The frigate is expected to provide backup to the French aircraft carrier Charles de Gaulle, which has already been sent to the eastern Mediterranean as part of the anti-Islamic State coalition.The debate was also to focus on the state of German weapons systems. According to a report of the Defence Ministry made available to dpa, only 66 of a total 93 Tornado fighter jets owned by the air force were operational, while only 29 were actually ready to use.Defence Minister Ursula von der Leyen does not see this as a problem. "Thirty Tornados are ready to use, and we only need six of them. This means we have enough wiggle room," she told public broadcaster ARD on Wednesday.She declined to give an estimate of the possible duration of the operation."The duration of the mandate will strongly depend on the success of the decisive political process," Von der Leyen said. Much also depended on the other powers in the region, such as Turkey, Qatar, Saudi Arabia and Iran."It will be a long mission, and it will be a difficult and dangerous mission," she added.Tuesday‘s decision by Berlin, which has been reticent to engage in military operations since World War II, comes in the wake of the November 13 terrorist attacks in Paris, which killed 130 people and was claimed by Islamic State.Since then, Chancellor Angela Merkel has pledged to provide any assistance to France, which has spearheaded efforts to forge the new coalition.The mission is expected to be approved by parliament.
