A series of natural disasters has struck Indonesia. More than 100 people were reported to have been killed by an earthquake and tsunami in a remote group of islands west of Sumatra. Shortly afterwards, the country's most active volcano Mount Merapi in central Java erupted, killing 13 people. Karishma Vaswani reports from Jakarta.

Officials in West Sumatra said the three-metre-high tsunami washed away at least 10 villages in the Mentawai islands, but getting information from the worst-affected parts of the islands has been challenging. Bad weather has meant no search and rescue teams have been able to arrive in the area as yet. Meanwhile, black ash and soot has been spewing out of Mount Merapi ever since it erupted. Officials say more than 13,000 people have to be moved away from the volcano to refugee camps nearby.
