Aftershocks have jolted central Croatia, a day after a 6.3-magnitude earthquake killed at least seven people, injured dozens and left several towns and villages in ruins.

The strongest 4.7-magnitude tremor was recorded near the heavily damaged town of Petrinja, some 40 kilometres (25 miles) south east of the capital Zagreb.
