Spokesman of the Greek government Gabriel Sakellaridis said on Thursday that Athens is ready to intensify the debt talks.

"The Greek delegation, as agreed, is ready to intensify deliberations in order to conclude a deal soon, even in the coming days," he said.

Earlier, the International Monetary Fund (IMF) spokesman Gerry Rice said that the IMF's technical team has left the debt talks in Brussels. The reason is "major differences", he noted. "There are major differences between us in most key areas," Rice said.
