Fighting continued throughout the 1990s, and was marked by two key assassinations carried out by the LTTE: those of former Indian Prime Minister Rajiv Gandhi in 1991, and Sri Lankan President Ranasinghe Premadasa in 1993, using suicide bombers on both occasions. The fighting briefly halted in 1994 following the election of Chandrika Kumaratunga as President of Sri Lanka and the onset of peace talks, but fighting resumed after LTTE sank two Sri Lanka Navy Fast Attack Craft in April 1995. In a series of military operations that followed, the Sri Lanka Armed Forces recaptured the Jaffna Peninsula. Further offensives followed over the next three years, and the military captured large areas in the north of the country from the LTTE, including areas in the Vanni region, the town of Kilinochchi, and many smaller towns. From 1998 onward, the LTTE regained control of these areas, which culminated in the capture in April 2000 of the strategically important Elephant Pass base complex, located at the entrance of the Jaffna Peninsula, after prolonged fighting against the Sri Lanka Army.
