"As an immediate reaction to the incidents in Poland, we will offer to strengthen air policing with combat air patrols over its airspace with German Eurofighters," defence ministry spokesman Christian Thiels said at a regular press conference.

"This can happen from tomorrow, if Poland so wishes," Thiels said.

The sorties would be launched "from German airbases" without needing to relocate the jets to Poland, he said.

Such patrols take place in "specific airspaces", which are "agreed exactly with the Polish side", Thiels said.

German Defence Minister Christine Lambrecht would seek to speak to her Polish counterpart on the matter today, he added.

Officials are racing to clarify the circumstances of the missile strike near the Polish village of Przewodow near the Ukrainian border, which killed two people.

German Chancellor Olaf Scholz earlier on Wednesday warned against any "hasty conclusions" about the incident.

Scholz stressed it was important to "make clear that this would not have happened without the Russian war against Ukraine".
