Germany’s parliament is due to vote on whether the country should provide military support in the fight against Islamic State (IS) militants in Syria.
MPs are expected to back the controversial plan, a BBC correspondent in Berlin reports.
Tornado reconnaissance aircraft, a naval frigate and a 1,200 soldiers will then be sent to the region. But German forces will not engage in combat.
The vote comes after a French appeal following last month’s Paris attacks.
On Thursday, British warplanes carried out first air strikes on IS targets in Syria after the country’s parliament authorised the military operation.
