Several thousand Turkish troops crossed into northern Iraq early Wednesday to chase Kurdish guerrillas who attack Turkey from bases there, two Turkish security officials said. Turkey's foreign minister denied its troops had entered Iraq.

Two senior security officials, speaking on condition of anonymity because they were not authorized to talk to the media, characterized the action as a "hot pursuit" raid that was limited in scope. They told The Associated Press it did not constitute the kind of large incursion that Turkish leaders have been discussing in recent weeks as Turkish troops built up their force along the border.

One official said the troops went less than two miles inside Iraq and were still there in late afternoon. "It is a hot pursuit, not an incursion," one official said.

Another official said by telephone it was "not a major offensive and the number of troops is not in the tens of thousands." He also said the Turkish troops went into a remote, mountainous area.

The officials are based in southeast Turkey, where the military has been battling separatist Kurdish rebels since they took up arms in 1984.

The officials stood by their statement despite denials from Turkish and Iraqi officials.

Turkey's private NTV television quoted Foreign Minister Abdullah Gul as saying reports of a cross-border operation were false.

"There is no such thing, no entry to another country. If such a thing happens, then we would announce it," Gul said. "We are in a war with terror, we will do whatever is necessary to fight terrorism."
