(Updates with new ship hijacked, previous MADRID) By Abdiqani Hassan BOSASSO, Somalia, April 21 (Reuters) - Somali pirates hijacked a ship en route from Dubai on Monday and Spain said it had sent a naval frigate after the seizure of a Spanish tuna fishing boat with 26 people aboard off Somalia. A surge in hijackings for ransom off lawless Somalia have made it one of the world's most dangerous shipping zones. The Dubai-flagged Al-Khaleej was carrying food for sale in Somalia when it was held up seven km (four miles) off the northeastern Somali port of Bosasso, authorities there said. "If these pirates have now gone ahead to hijack vessels bringing us food, this will badly affect activities at our port. We need to do something about them," said Abdisamad Yusuf Abwaan, commerce and industry minister for the semi-autonomous northeast Puntland region. Suspected Somali pirates also fired on a Japanese-flagged chemical carrier off Yemen on Monday. And Madrid said it had sent a naval frigate to help rescue the Spanish tuna fishing boat, which was attacked on Sunday. The attackers appear undeterred by French troops' arrest in the desert last week of six Somali pirates who seized a French luxury yacht and held its crew hostage for a week. They were flown to France for questioning. The Spanish Foreign Ministry said 13 of the people on board the tuna fishing boat, called Playa de Bakio, were Spanish, and added it was in touch with governments with military presence in the area to help find the vessel. Spanish national radio quoted the captain of the boat as saying everybody on board was well. A man who said he was one of the captors said in broken English that the pirates were Somalis and wanted money. Somali authorities said the hijackers were taking the Spanish boat to Garad port, in south Puntland. Somalia has been without an effective central government since the 1991 toppling of a military dictator, allowing anarchy and violence to flourish. Kidnapping and piracy are lucrative businesses and most Somalis treat their captives well in anticipation of a ransom. A Kenyan-based regional maritime group, the Seafarers' Assistance Programme, said suspected Somali pirates fired at a Japanese-flagged chemical carrier off Yemen on Monday, causing minor damage but no injuries.
