The "La Penca bombing" refers to a bomb attack on May 30, 1984, in the guerrilla outpost of La Penca in Nicaragua, near the Costa Rican border. The bomb attack occurred during a press conference being conducted by Edén Pastora, a Contra leader, who is presumed to have been the target. Seven people, including three journalists, were killed in the attack.
A press conference had been arranged in the guerrilla outpost of La Penca by Edén Pastora, a former Sandinista who had switched allegiance to the Contra rebels. The press conference took place in an enclosed hut on stilts near the northern bank of the San Juan River that separates Costa Rica from Nicaragua. The press conference had been convened by contra officials in the Costa Rican capital of San José, and the journalists arrived to La Penca in the middle of the night after a traveling all day over land and by canoe from San José. Because of the late hour, Pastora initially asked that the press conference commence in the morning, but as the reporters began peppering the guerrilla leader with questions an impromptu press conference began as the reporters and television news crews gathered with Pastora around a chest-high table situated in the main room of the hut.
The bomb is believed to have been hidden in an aluminum camera case, and planted by an individual carrying a stolen Danish passport. According to witnesses, the bomber used the name Per Anker Hansen and claimed he was a Danish photographer. Afterwards, bombing survivors commented that they found it odd that "Hansen" had so zealouly guarded his "camera equipment", wrapping the unwieldy aluminum box in plastic. "Hansen" is believed to have deposited the camera case containing the bomb underneath the table. News footage later showed the suspected bomber gesturing to his camera as if to indicate an equipment malfunction as a pretext to leave the room. The bomber is suspected to have detonated the bomb remotely using a walky-talky signal as a detonator. Seconds after "Hansen" left the room, an explosion ripped through the hut, leaving the injured and dying crying out in pain and calling for help in sudden darkness.
