Security forces in Dubai have released the names and photos of 15 more people, whom they believe were involved in the assassination of a senior Hamas official at a luxury hotel.

Six of those believed to be responsible for the death of Mahmoud al-Mabhouh had UK passports, while the rest had Irish, Australian and French documents. Dubai police say the newly named suspects provided "logistical support."

"The new list of suspects includes people who offered prior logistical support and preparations to facilitate the crime, and others who played a central role," said a statement released on Wednesday.

The new suspects raise the number of suspects involved in the killing of a senior Hamas commander to 26 people, all Western passport holders.

Dubai Police Chief Dahi Khalfan Tamim had earlier said investigations revealed that Mossad, Israel’s spy agency, was behind the assassination of al-Mabhouh.

The top Hamas official was killed in his hotel room on January 19, hours after he arrived in Dubai from Syria.

The Dubai police had previously identified 11 people, 10 men and a woman, suspected of murdering Mabhouh. According to the police, the suspects had arrived in Dubai the day before the killing.

Interpol has issued Red Notices for the 11 suspects.
