BRUSSELS, April 7 - EU officials will meet Ukraine's energy minister on Tuesday as well as review the bloc's own gas storage levels as fears grow that rising tensions between Moscow and Kiev might lead to a cut-off of gas supplies, Reuters reported.

At midnight a deadline expires for Ukraine to reduce the $2.2 billion debt it owes Moscow for natural gas deliveries. So far Ukraine has offered no payments, Moscow says, raising the risk of supply disruption, with possible knock-on effects for the European Union.
