Israel has denounced the blasts that ripped through two Istanbul synagogues on this morning, killing at least 15 people, as "criminal terror attacks".
"Terror is terror whether it targets Jews or non-Jews," the Foreign Ministry said in a statement.
The ministry also said it had offered aid to Turkey. The Jewish Agency, which deals with Jewish diaspora affairs, was sending a delegation to Turkey.
A radical Turkish Islamist group known as IBDA/C claimed responsibility for the two blasts in which police officers at the scene said as many as 24 people were killed. The Turkish interior ministry put the death toll at 15, with 146 injured.
