Meaningful progress has been made in the investigation into Monday's bus bombing in Jerusalem, which left 16 people wounded, according to Israel's Channel 2.

Further details have not been released for publication, as part of a gag order into the ongoing investigation.

At this point, investigators believe that the most seriously injured person recovered from the scene is the terrorist who planted the bomb.

The explosive device was relatively rudimentary, and investigators are working on the assumption that the terrorist had not in fact intended to be a suicide bomber, but that his bomb accidentally went off prematurely. The unidentified man is currently in critical condition.

Two other people were seriously wounded in the blast, which engulfed two buses in flames; the remaining 13 victims are all listen in moderate to light condition - many of them with multiple shrapnel wounds.

All the casualties are hospitalized in Jerusalem's Shaarei Tzedek and Hadassah Ein Kerem hospitals.

Jerusalem Police have raised their alertness level for the upcoming Passover festival, during which Muslim terrorists have in the past attempted to target Jews celebrating the seven-day holiday. Among other precautions, the police presence in the capital has been considerably boosted, particularly at tourism hotspots.
