The illegal search of a private Turkish-flagged ship by a German frigate is a border violation, a Turkish opposition leader said on Tuesday.
This unlawful move is a national security issue for Turkey, according to Meral Akşener, chairwoman of the Good (IYI) Party.
"The illegal search of a Turkish-flagged ship by a German frigate under the rule of a Greek commander is a border violation because a vessel in international waters is considered the territory of its country of origin," she said in a meeting of her party's parliamentary group.
Akşener said German authorities should have contacted their Turkish counterparts if they had any doubts over the ship or its cargo.
"However, they preferred to do exactly the opposite. We cannot pass this off as a simple mistake," she stressed.
"I expect the government to take the necessary steps to protect our rights as guaranteed under international law."
Turkey has strongly condemned the illegal search of the Turkish-flagged MV Roseline A by an EU naval mission on Sunday.
The German frigate responsible for the unlawful action was part of Operation Irini, a European mission launched earlier this year to enforce the UN arms embargo on Libya.
The Turkish Foreign Ministry said the vessel was only carrying paint, paint materials, and humanitarian aid to Libya's port of Misrata, and did not violate the UN embargo.
The ministry also summoned envoys of the EU, Italy, and Germany on Monday.
A diplomatic note given to the envoys said "the incident is against international law and that our rights to compensation are reserved," according to the ministry.
Turkey has long argued that the UN embargo is being enforced in a biased manner favoring warlord Khalifa Haftar.
Libya has been torn by a civil war since the ouster of Muammar Gaddafi in 2011.
A new government was founded in 2015 under a UN-led agreement, but efforts for a long-term political settlement have failed in the face of attacks by Haftar's forces.
Turkey supports the country's legitimate government, based in the capital Tripoli.
