We’re learning more about a young Israeli-American who is among three teenagers abducted in the West Bank. Authorities say terrorists kidnapped the group while they were hiking on Thursday. Meanwhile, there has been an outpouring of support for 16-year-old Naftali Fraenkel.

Naftali’s aunt, Ittael Fraenkel, told reporters that the family is worried, but optimistic.

“We really, really want to see him home fast. We miss him and we love him,” she said, adding, “but we know and we believe that Israeli authorities, the police, and the Army and intelligence are doing the utmost that could be done at this moment.”

Israeli police have arrested dozens of Hamas members in connection with the abductions. On Sunday, Secretary of State John Kerry joined Israel in implicating Hamas, calling the move a “despicable terrorist act.”

Despite praising the kidnappings, Hamas has denied accusations that it was responsible.

Palestinian Authority President Mahmoud Abbas on Monday condemned, for the first time, the kidnapping last week of three Israeli teenagers, who Israel says were abducted by members of the Islamist militant movement Hamas.

In a written statement in Arabic, Abbas also denounced the subsequent Israeli response to the kidnappings, a massive military sweep in the West Bank in which one Palestinian has been killed and hundreds of Hamas officials and others have been arrested.

According to Palestinian officials, a 20-year-old Palestinian was killed and another was wounded during clashes with Israeli forces early Monday as they conducted house-to-house searches in al-Jilazoun refugee camp outside Ramallah, Reuters news agency reported.

“The Palestinian presidency condemns the series of events that happened last week, beginning with the kidnapping of three Israeli youths,” Abbas’sstatement said. “The presidency reaffirms the importance of neither side resorting to violence.”
