Others landed near President Touré's summer house, which they burnt.[4] The invaders concentrated on destroying the headquarters of the African Party for the Independence of Guinea-Bissau and the Cape Verde Islands (Partido Africano da Independência da Guiné e do Cabo-Verde — PAIGC) in an unsuccessful attempt to capture PAIGC leader Amilcar Cabral, who was in Europe at the time. Others seized the political prison camps and liberated a number of prisoners, including Portuguese soldiers and airmen who had been captured earlier by PAIGC forces and turned over to the Guineans for safekeeping; some had been held captive in these camps for as long as seven years. The main attacking force reached but ignored the airport and apparently attacked what they thought was the operative radio station, unaware that its use had been discontinued when replaced earlier by a new station.
