LONDON, May 12 (Xinhua) -- British and European foreign ministers and officials met in London on Monday but concluded without substantial breakthroughs on the situation in Ukraine.

According to a statement from the British Foreign, Commonwealth and Development Office, the ministers reaffirmed their commitment to providing security guarantees for Ukraine, including the establishment of a coalition of air, land, and maritime reassurance forces.

Foreign ministers from France, Spain, Germany, Italy, and the European Commission reiterated that a halt remains a prerequisite for further diplomatic progress.

However, British Foreign Secretary David Lammy, the host, refrained from commenting on the sequencing of a potential ceasefire.

Monday's meeting is viewed as a part of the preparations for the upcoming UK-EU Summit, scheduled to take place next Monday in London.
