Colombo, Mar. 23: Briefing documents prepared by the United Nations have warned of a major humanitarian crisis in Sri Lanka, where over 150,000 people are being shelled at daily and are running short of water and medicine.

The Sri Lankan Government has declared the area in question as a "No Fire Zone", and the UN claims that tens of thousands of people are caught between the last 1,500 fighters of the Liberation Tigers of Tamil Eelam (LTTE) and the advancing troops of the Sri Lankan army.

Colombo – The navy thwarted an attempt by rebels to carry out a mid-sea suicide attack off north-eastern Sri Lanka, killing all five insurgents, a military spokesman said Monday.

He said the attackers posing as civilians fleeing the rebel-controlled areas of Mullaitivu, 390 kilometres north-east of the capital, were in a dinghy coming along with three other boats carrying civilians when they were detected.

In a shocking development, a 12 year old girl student died and 27 others were hospitalized after being administered a shot of Rubella vaccine in Sri Lanka's Matara district.

The girl, Piyasala Hansani, died at his school St. Thomas' Girls School, about 160 km south of the capital Colombo.

It can be recalled that nearly 300 students of the school were given vaccine after which some students had fallen ill and were admitted to the hospital.

Colombo - Government troops have cornered the Tamil rebels in an area of 24 square kilometres in northern Sri Lanka, Prime Minister Ratnasiri Wickremanayake said Thursday.

"We have eliminated terrorism from most parts of the country and will be able to report that terrorism has been eliminated from the entire country within days", Wickremanayake told parliament.

Geneva - An aid worker was killed in the conflict area in northern Sri Lanka, the humanitarian organization CARE International said Wednesday.

R. Sabesan, aged 24, worked for CARE and was hit in a shelling Tuesday in the so-called no-fire zone. He later died of his wounds as he was unable to access medical care, the aid group said.

"The toll this war is taking on civilians is devastating," said Nick Osborne from CARE in a statement. "Humanitarian workers trapped in the conflict zone are just as much at risk as anyone else."
