Britain said flights to and from Belfast and other parts of Northern Ireland would be halted from 0600 GMT to 1200 GMT on Sunday because of an ash cloud from an Icelandic volcano. The National Air Traffic Service's statememt marked an extension of a previous no-fly decree issued on Saturday night that excluded Belfast, Reuters reported.
In April, ash from the volcano caused widespread disruption across Europe when a number of countries closed their airspaces for nearly a week as a safety precaution.
Since then the ash has periodically forced the short-term closure of parts of airspace in some European countries.
