The safe-haven Japanese yen strengthened on Tuesday after deadly attacks in Turkey and Germany. However, the yen dropped back after the Bank of Japan kept its rates unchanged.

The attacks on Monday caused stocks to pare their gains as treasuries prices rose and the yen firmed.

An attack in Berlin killed at least 12 people and injured another 50.

The Turkish Lira fell after the Russian ambassador to Turkey was fatally shot in Ankara while the Russian Rouble recovered slightly against the dollar. That came after the lira and rouble both fell to session lows against the dollar on Monday.
