At least 14 people have been killed in a suicide bomb attack in southern Sri Lanka, police say.
The telecoms minister was among about 35 people injured in the blast at the town of Akuressa, 160km (100 miles) south of the capital, Colombo.
Government officials were attending a function at a mosque to celebrate an Islamic holiday at the time.
The defence ministry said the blast was carried out by Tamil Tiger rebels but no-one has yet admitted responsibility.
The Sri Lankan government has strongly condemned the attack. It urged people to remain calm and not to be provoked.
'Ministers targeted'
"An LTTE [Liberation Tigers of Tamil Eelam] suicide bomber has attacked a mosque at Godapitiya, in Akuressa, in the Matara district," the defence ministry said on its website.
Sri Lanka's oil minister AHM Fowzie, who was at the site, told Reuters news agency the bomber appeared to have targeted six ministers as they walked in a procession toward the mosque.
"This is an area where nobody expected a thing like this to happen," he said.
The ministers were attending a ceremony to mark the birthday of the Prophet Muhammad when a bomber on a bicycle set off the explosion behind them, officials told the BBC.
Post and Telecommunications Minister Mahinda Wijesekara was injured in the attack and is said to be in intensive care.
A helicopter has airlifted the critically wounded back to Colombo. One witness, Ahamed Nafri, told Associated Press he was walking toward the mosque at the time of the blast.
