Liquids, creams and gels may be banned from hand luggage on European flights under new rules being discussed by EU countries in the aftermath of a suspected bomb plot in London last month, sources familiar with the talks said.

They said the new rules could severely limit the size of carry-on bags and prohibit passengers from carrying items such as toothpaste and hand lotion throughout the European Union.

Security experts from the 25 EU member states met in Brussels this past week to discuss potential changes, and another meeting is scheduled for Sept. 6-7.

The European Commission declined to comment.
