MUMBAI, India (AFP) — India on Monday marked the tenth anniversary of the Mumbai terror attacks with ceremonies at sites across the city that became battlegrounds in the wave of violence that killed scores and dealt a critical blow to relations with neighboring Pakistan.

Armed with AK-47 assault rifles and hand grenades, ten Islamic militants killed 166 people and injured hundreds more in a three-day rampage through India’s financial capital which started on Wednesday November 26, 2008.

Ten years on, the United States has offered a new $5 million reward for the capture of the remaining attackers and called on Islamabad to cooperate with the hunt for the planners of the assault.

The attackers belonged to Pakistan-based militant group Lashkar-e-Taiba (LeT).

At a solemn ceremony Mumbai’s police remembered more than a dozen officers and commandos killed in the operation against the militants.

Relatives of the victims and local dignitaries laid wreaths and sprinkled rose petals at a police memorial honoring the dead while the force’s brass band played the “Last Post.”

“A grateful nation bows to our brave police and security forces who valiantly fought the terrorists during the Mumbai attacks,” said Prime Minister Narendra Modi, who called the attacks “gruesome.”

Played out on TV news channels around the world, the bloody events — widely known as 26/11 — have been compared in India to New York’s suffering on September 11, 2001.

The coordinated attacks on the city of nearly 20 million people hit luxury hotels, the main railway station, a restaurant popular with tourists and a Chabad center.

Wanted leader

Residents and railway officials also paid their respects at Chhatrapati Shivaji Terminus train station where Mohammed Kasab, the only gunman caught alive, and another attacker killed almost 60 people and wounded at least 100 others.

The Taj Mahal Palace and Tower Hotel will hold a private service to remember the 31 people who died there.

Over 60 hours, four attackers shot dead guests and hotel staff, detonated explosives and set ablaze parts of the building — including its famous dome.

Dramatic scenes of Indian commandos battling the heavily armed gunmen, and guests attempting to escape from windows down bedsheet ropes were beamed around the world on live television.

Indian security forces only retook control of the hotel on the morning of November 29.

More than 30 people died at the Oberoi and Trident hotels in a 42-hour siege involving shootings, explosions and hostage-taking.

Six hostages — including a rabbi and his pregnant wife — were killed at the Nariman Chabad House.

The current rabbi is to unveil a new memorial at the center to all those who died in the 26/11 attacks.

Kasab, the gunman caught at the railway station, was executed by India in 2012 after being found guilty of charges including murder and waging war against India.

The LeT called him “a hero” in a comment that highlighted the deep-rooted rivalry between India and Pakistan since their division in 1947.

Indian politicians and officials routinely condemn Pakistan for not taking action against LeT leader Hafez Saeed who remains free even though he is designated a terrorist by the United Nations. Pakistan says that evidence provided by India against Saeed is too vague.

Six Americans were among the Mumbai victims and the US State Department announced a $5 million prize for the capture of the remaining planners of the attacks.

The United States already has a $10 million bounty offered for Saeed and $2 million for Hafiz Abdul Rahman Makki, another senior group leader.

“It is an affront to the families of the victims that, after 10 years, those who planned the Mumbai attack have still not been convicted for their involvement,” US Secretary of State Mike Pompeo said in a statement.

“We call upon all countries, particularly Pakistan, to uphold their UN Security Council obligations to implement sanctions against the terrorists responsible for this atrocity, including Lashkar-e-Tayyiba and its affiliates.”
