DNA evidence left on SIM cards helped leader Bulgarian investigators to conclude that Hezbollah was indeed behind the bus bomb attack in Burgas in which five Israelis and one Bulgarian were killed, Ha’aretz reported.

Bulgarian Foreign Minister will present the evidence of Hezbollah’s guilt in a briefing to other E.U. Foreign Ministers today.

The U.S., Israel and Canada are pressing the European Union to label Hezbollah a terrorist organization, which would make it harder for the Lebanon-based terrorist group to raise funds.
