Amid a unilateral ceasefire, Turkey, assisted by NATO, threatened Syria with war, forcing Abdullah Öcalan to leave Syria. Öcalan headed for Europe to promote a political solution to the Kurdish question.

That day, the international conspiracy began. Öcalan arrived in Athens from Syria on 9 October 1998. On 11 October he arrived in Moscow.

On 20 October, Turkey, Syria, and Lebanon signed the Adana Protocol. Turkey-Syria relations "quickly improved."

On 4 November, the Duma, which is the lower legislative house of the Russian Federation, asked for the recognition of asylum for Öcalan with 298 votes in favour, and 1 against.

On 12 November,  Öcalan left for Rome, but on 16 January 1999, he left the Italian capital to fly back to Moscow, from where, on 29 January, he flew to Greece.

On 31 January, Öcalan tried to go to Belarus and the Netherlands; neither country allowed him to land. On 1 February, he returned to Athens. On 2 February, Greek officials took Öcalan to the Greek embassy in Nairobi en route to South Africa.

But on 15 February 1999, he was kidnapped from Nairobi, Kenya's capital, in an international clandestine operation and brought to Turkey.
