SONGKHLA - A man was killed and 11 others, including a child, were injured in a bomb attack in Thepha district at about 7pm Tuesday.

It was the second deadly attack in Songkhla province in a week.

Police said the killer bomb Wednesday evening was hidden in a motorcycle parked behind the Thepha train station.

About 30 minutes before the bomb exploded, police were informed about a suspicious object attached to a mobile phone inside a grocery store, near the train station. The motorcycle bomb went off after officers arrived at the store.

The man killed in the blast was identified as Chom Phetchamras. He died in hospital.

Reports on social media said the child injured was an 11-year-old girl.

It was the second bomb in Songkhla province in nine days. A bomb attack just before Songkran inChana district killed a policeman and wounded another officer on April 11.

Separatists in the deep South claim the three southernmost provinces of Narathiwat, Pattani and Yala, as well as half of Songkhla, were taken and occupied illegally from the Malayan king in the early 20th century.

In the first and second major uprisings in the 1960s and 1970s, they staged many attacks in Songkhla, including in the province's major city, Hat Yai, the largest in the South.

The third uprising, which began in January, 2004, has centred mainly on the three southern provinces, but there have been major attacks on Hat Yai and other Songkhla sites as well.
