By Sumit Sharma Nov. 26 (Bloomberg) — Mumbai residents will today mark the first anniversary of a three-day assault on the city by Pakistani gunmen that forced a security overhaul in India’s financial hub and capsized peace talks between the two nations. Employees at the Taj Mahal Palace & Tower on the city’s southern Colaba waterfront will install a memorial near where thirty-one people died in the hotel’s rooms and restaurants as gunmen opened fire and threw grenades during a 60-hour rampage. Police will parade near Chowpatty beach where an officer was killed detaining the only militant to survive the attacks. The city’s business community will be at work in offices that are better protected than a year ago while still vulnerable. “You have to get on with life,” said Andrew Holland , the chief executive officer at investment manager Ambit Capital in Mumbai. “Terrorist attacks can happen anywhere,” he said. Mumbai is as central to operating in India as London and New York are to doing business in the U.K. or U.S., he added. The Nov. 26-29 raid by 10 terrorists left 166 dead and marked a shift in strategy for anti-India groups, targeting Westerners staying at luxury hotels along with the city’s main railway station and a popular bar. The attacks struck at the international links that helped the country’s economy grow at 9 percent in the three years leading up to the killings. Investors have looked past the terrorist threat to focus on India’s growth potential. After slumping by half in 2008, the benchmark Sensitive Index has climbed 78 percent since Jan. 1, poised for the best annual return in 18 years as global funds invested $15.3 billion in shares of local companies. Security Measures Some businesses have responded. Oil and Natural Gas Corp. , India’s biggest oil explorer, will spend $86 million on security this year, buying speed boats to guard oil wells off Mumbai and installing electronic surveillance systems, Chairman R.S. Sharma said last week. Shopping malls have installed metal detectors and armed police patrol outside hotels, the most visible signs of increased vigilance. There are also plans to recruit more police, and elite commandos are now based near four major cities. Nonetheless progress has been slow. “None of this will be close to altering the risk profile of the country,” Ajai Sahni , executive director of New Delhi’s Institute of Conflict Management, said in a telephone interview. Home Minister Palaniappan Chidambaram “has said India remains as vulnerable to terrorist attacks today as it was on 26/11,” Sahni said, using the date the attacks started in the same way New Yorkers refer to 9/11. “It’s a very sober and sobering assessment.” Mixed Targets Soon after the attacks 6,000 new positions in intelligence agencies were approved, Sahni said. “They have actually recruited not more than a hundred.” Still, the government has shown a “great measure of seriousness” in its efforts to make the country a safer place to live and invest, he said. Mumbai is home to both of India’s main stock exchanges as well as being the primary trading center for commodities, bullion, diamond, bonds and currencies. Security checks are commonplace, “but there is not much sense of security,” said Devesh Kumar , managing director of Mumbai stockbroker Centrum Broking Pvt. There have been no terrorist attacks in India since Mumbai, which was preceded in 2008 by bombings in major cities including Jaipur, Bangalore, Ahmedabad and the capital, New Delhi. “We live in a neighborhood which is the epicenter of terror,” Chidambaram, drafted into the Home Ministry hours after the attacks to oversee the response, said Nov. 12. “Some of this is spilling over into India. We have to learn to live with it.” Slow to React The gunmen arrived in Mumbai in the evening aboard a dinghy as commuters headed home. They spread out in groups, leaving bombs in two taxis and opening fire at the railway station and a bar popular with locals and foreign tourists. Mumbai police were slow to realize the scale of the attack and federal forces arrived late — it took more than nine hours for commandos to land from Delhi. The militants opened fire at the Taj and nearby Trident and Oberoi hotels, favored by business executives, before torching rooms and digging in. Among the victims were Ashok Kapur , the 65-year-old chairman of YES Bank Ltd., partly owned by Rabobank of the Netherlands, who was killed as he dined at the Oberoi with his family. Paul Polman , now the chief executive officer of Unilever Plc, and his predecessor, Patrick Cescau , survived the siege at the Taj. Gunmen also took over a Jewish center, where five Israelis died. Nationals from the U.S., the U.K., and Germany were also killed. Nuclear Rivals India blamed the Pakistan-based militant group Lashkar-e- Taiba for the attack and demanded the government in Islamabad act against it. Peace moves were halted. The two nuclear-armed nations have fought three full scale wars and been involved in several skirmishes since independence in 1947. Pakistan acknowledged the raid was planned on its soil. Yesterday an anti-terrorism court charged seven people, including Zaki ur-Rehman Lakhvi , a Lashkar commander, with involvement in the attacks. The group’s founder has been put under house arrest. While leaders from the two countries have met in recent weeks, India insists a return to full talks is still a long way off. The lone surviving gunman, Mohammed Ajmal Kasab , is on trial in a Mumbai court. To contact the reporters on this story: Sumit Sharma in Mumbai at sumitsharma@bloomberg.net .
