A senior European Union (EU) official on external relations on Wednesday expressed opposition to Israel's unilateral actions in resolving the Israel-Palestine issue.

"We strongly believe that Israel's legitimate security concerns cannot be met through unilateral action or decisions imposed by force: only a negotiated settlement will be sustainable," said Benita Ferrero-Waldner, European Commissioner for External Relations and European Neighbourhood Policy.

Ms Waldner voiced the EU's position in a speech to the plenary session of the European Parliament in Strasbourg of Fance. This is the first comprehensive expression of the EU's position on the Middle East after the Israeli elections.

"The EU would only support changes to the pre-1967 borders agreed by consensus between the Parties: we support a two-State solution leading to a final and comprehensive settlement of the conflict, with Israel and a Palestinian State living side-by-side within secure and mutually recognized borders," she said.

"We should underline to our Israeli partners the importance of refraining from actions that may prejudice final status negotiations," she added.

After Israeli acting prime minister Olmert on Kadima's election victory, the EU has extended congratulations and closely watched the changing situation in the Middle East.

According to Ms Waldner, the EU "stands ready to work with" the next Israeli Government to promote security and peace for Israelis and Palestinians alike.

In the meantime, Ms Waldner also sent a clear warning to the new Palestine government.

"There can be no compromise on the Quartet principles," she said.

"We expect the new Palestinian government to commit to the principles of non-violence, recognition of Israel and acceptance of previous agreements and obligations, including the Roadmap," she added.

"Unless the new government complies with the Quartet conditions for continued engagement, there can be no 'business as usual'," she stressed.
