Two almost simultaneous grenade attacks in the Kenyan port city of Mombasa and a nearby small town late Saturday killed one person and wounded at least 24 others.

Officials say unidentified attackers threw a grenade at a Christian religious gathering in Mtwapa, a town north of Mombasa, killing a woman and wounding more than 20 people.

In Mombasa, a second grenade attack was carried out against a restaurant near the city's main stadium. There were reports of two people wounded in that attack.

Kenya has seen several hit-and-run grenade attacks in the capital, Nairobi, since Kenyan troops entered neighboring Somalia last October to fight the radical Islamist group al-Shabab. But this was the first incident in Mombasa, a popular holiday destination.

This is the latest in a string of grenade attacks on the capital since Kenya sent troops into Somalia in October to fight al Qaida-aligned al-Shabab militants.

In early March, a grenade attack in Nairobi killed at least four people and injured about 40 others.

Kenya's government blames the al-Qaida-linked group of attacking and kidnapping foreign tourists on its territory. But Al-Shabab has denied involvement in recent grenade attacks in Kenya.
