LONDON, July 9 (Reuters) - The dollar eased on Wednesday as oil prices rebounded, after geopolitical tensions were pushed back onto investors' radar by news of Iran test-firing missiles and of an armed attack on the U.S. consulate in Turkey.

Iran's state media reported Iran had test-fired nine long- and medium-range missiles, including one which it has previously said could reach Israel and U.S. bases in the region.

Tensions in the region were further stoked after three policemen and three gunmen were killed in an attack on the United States consulate in Istanbul.

Also in Turkey, three German tourists were kidnapped by Kurdish guerrillas, broadcaster CNN Turk reported a local governor as saying.
