Sri Lankan military officials say air force jets destroyed a training base for Tamil Tiger rebels Thursday in the north of the country.

A Sri Lankan Air Force spokesman said the base was a "suicide training facility" in rebel-held territory in the jungle.

Also Thursday, Sri Lankan officials said at least four people were killed and 13 others wounded when a suicide bomber riding a bicycle blew himself up in the north. 

The military blamed Tamil Tiger rebels for the attack, which happened in the northern Jaffna peninsula. 

Sri Lanka's government formally pulled out of a 2002 Norwegian-brokered cease-fire with the rebels earlier this month.  

At least 70,000 people have been killed since the rebels began fighting for an independent homeland in 1983 - claiming discrimination by Sri Lanka's majority-Sinhalese population.  The Tamil Tigers already control much of the island's north.
