PARIS (AP) Striking workers again closed down the Eiffel Tower on Wednesday, the third day running that the landmark expected to be at the heart of celebrations for the Paris Olympics has been off-limits to visitors.

A message on the towers website also warned of more possible disruptions Thursday, if strikers continue their push for salary hikes and other concessions.

We apologize for the inconvenience, the message said.

One of the strikers representatives, Denis Vavassori of the CGT union, has previously warned that their protest action could go on for several days, even weeks. The operator of the 330-meter (1,083-foot) tower has not responded to requests for comment.
