An ash cloud from Iceland could reach British airspace later this week, but a British official says the country is better prepared after an eruption last year shut down airports for five days.

British Foreign Secretary William Hague told reporters in Brussels on Wednesday that Britain has more information on how ash clouds move and is less likely to have to enforce a blanket flight ban.

Iceland shut its main airport Sunday after the Grimsvotn (GREEMSH-votn) volcano about 120 miles (200 kilometers) east of Reykjavik erupted. London's Met Office says the ash may reach British airspace later this week.

European flights were grounded last year after the Eyjafjallajokull (ay-yah-FYAH-lah-yer-kuhl) volcano erupted, leaving 10 million travelers stranded around the world.
