In a fresh blow to beleaguered LTTE, Sea Tigers' deputy chief Cheliyan was killed by the Sri Lankan forces which moved deeper into the fast-shrinking rebel territory in the embattled north.

Cheliyan, the second-in-command of the Sea Tigers, was killed in Kariyamullivaikkal on Friday in the clashes with Sri Lankan forces which captured an enemy earth bund, the Media Centre for National Security (MCNS) said on Sunday.

The death of senior LTTE leader was confirmed by intercepts of the Tamil Tigers' communications, the army said.

Meanwhile, few soldiers suffered minor injuries in an IED blast which took place during operations in the Akkarayankulam in Mullaittivu on Saturday, the ministry said.

The search operations in the area lead to the discovery of an LTTE training centre and a huge cache of military hardware.

The troops further advanced into the no-fire zone capturing LTTE positions in general area Karaiyamullivaikal on Saturday, the ministry said.

According to the sources, hours-long fighting took place in the area as Tamil Tigers launched stiff resistance on advancing troops.

Troops, however, breached the enemy defence line inflicting heavy damages to them, the defence ministry said.

The LTTE rebels had laid land mines heavily in the area to obstruct the security forces' advances, sources said.

Intercepting LTTE communication channels, Electronic Warfare sources confirmed that several LTTE militants were killed during the fighting, the ministry said.

In subsequent clearing operation in the area, troops found two bodies of LTTE rebels.

Meanwhile, Lankan forces continued their offensive march to rescue the civilians held hostage by the LTTE. After capturing the LTTE built earth bund in general area Karaiyamullivaikal, troops advanced further neutralising enemy pockets, military sources said.

Meanwhile, troops also uncovered a large consignment of LTTE military items from general area Puthukkudiyirippu, a report said.
