The European Union has stepped up its sanctions against Syria in response to the crackdown by President Bashar Assad's regime.

EU Council headquarters said in a statement Friday that it had slapped travel bans on seven more people, and frozen both their assets and the assets of six more "entities" — usually banks, institutions or companies.

No details of who was covered by the action were released. They will be made public when the sanctions are published in the EU's official journal on Saturday.

The statement said that "as the situation in Syria continues to deteriorate, the Council has reinforced EU restrictive measures against sponsors of the Syrian regime."
