Page "History of Guinea" Paragraph 14

In 1970, Portuguese forces, from neighboring Portuguese Guinea, staged Operation Green Sea, a raid into Guinea with the support of exiled Guinean opposition forces.

Among other goals, the Portuguese military wanted to kill or capture Sekou Toure due his support of the PAIGC, a guerilla movement operating inside Portuguese Guinea.

After several days of fierce fighting, the Portuguese forces retreated without achieving most of their goals.

The regime of Sékou Touré increased the number of internal arrests and executions.
