Dubai police chief Dahi Khalfan Tamim said on Friday that Israel should allow Dubai to conduct DNA tests on Israelis that Dubai suspects of participating in the assassination of senior Hamas operative Mahmoud al-Mabhouh in January.

"I call on Israel to bring the suspects for DNA tests, so it can be compared to DNA found at the scene," Tamim told the Al-Halij newspaper published in the United Arab Emirates. "If the results don't match, I will resign from my post."

A week ago, Dubai police reported that they had DNA from at least one suspected assassin. In an interview with the Al-Arabiya television station, Khalfan said that police also have the fingerprints of additional suspected members of the hit squad.

A Haaretz probe found that the passport photographs of suspected agents who allegedly assassinated al-Mabhouh were doctored so the agents would not be identified.

Various features of the people in the photographs, such as eye color or the line of a lip, were changed - slightly enough so as not arouse suspicion at passport control, but still enough that the real agent could not be recognized.
