On November 1, 1976, the MPAIAC began its terrorist activities through the Guanche Armed Forces, detonating an explosive in the
Galerías Preciados in Las Palmas de Gran Canaria. Following this attack in the Canary Islands capital, further attacks targeted the Canary Islands tourism sector, attacking a hotel, numerous tourist offices and travel agencies, for example in 1976 MPAIAC blew up a shopping center in Las Palmas de Gran Canaria. The MPAIAC supported El Rubio, murderer of the industrialist
Eufemiano Fuentes and, at the end of 1976, facilitated his escape to Algeria. On March 27, 1977, a bomb exploded in the flower shop of the passenger terminal at
Gran Canaria Airport in Las Palmas, injuring 7 people, and a second bomb was announced at the airport, forcing the police to cut off air traffic while they searched for the bomb. The chain of events forced the closure of the airport, diverting traffic to
Los Rodeos Airport in
Tenerife, 120 km (75 mi) away and contributing to the
runway collision nearly four hours after the initial bombing, the deadliest accident in aviation history. Antonio Cubillo, secretary general of the movement, denied responsibility for the accident, saying "[t]hat was the fault of the control tower at Las Palmas. We had nothing to do with it." He also noted that the group had warned tourists to stay away from the Canaries. That same month MPAIAC militant Santiago Marrero entered the
La Isleta barracks (Las Palmas) to steal weapons, dying in a shootout with the Navy soldiers attempting to arrest him. On the Spanish mainland, on Tuesday, June 14, 1977, the day before the
general elections, they attacked
Pescanova in
Madrid. On January 2, 1978, they hijacked the ship
Antonio de Armas, which was headed to
Valencia from Las Palmas, and diverted it to
Oran. In the early hours of February 3, a bomb exploded at the
Cervantes monument in Madrid. On February 24, 1978, the terrorist activity of the MPAIAC caused an unintentional fatality in the attack on
BBVA in
La Laguna, Tenerife. Police
bomb disposal specialist Rafael Valdenebro was mortally wounded while trying to deactivate the bomb planted by the MPAIAC. Valdenebro, 27 years old, was struck by fragments in the head, arms and legs and died 12 days later on March 8. == 1979: Cubillo's expulsion ==
