A low-magnitude tremor hit Bangladesh on Saturday, the national meterological service said, a day after a powerful earthquake struck outside the capital Dhaka and killed at least 10 people. The epicentre of the 3.3-magnitude tremor was in Ashulia, just north of the capital, the meteorologist told AFP. Aftershocks such as this are common after major earthquakes, but for some in Bangladesh it has added to fears of an even greater disaster.
