Dozens killed in Mumbai explosions

At least 50 dead in two explosions in Mumbai, India.

As many as 46 people were killed Monday, and 150 injured, when a pair of car bombs exploded in India's commercial capital, Mumbai.

The first blast ripped through a busy jewelry market. Minutes later, another explosion followed near one of the city's most popular tourist attractions: the Gateway of India.

So far, no one is claiming responsibility for the attacks. But police are focusing their investigation on Muslim militant groups.

The explosions caused chaos and devastation in two of the busiest parts of Mumbai.

The first bomb reduced a crowded market to mangled cars, broken glass and pools of blood. The bomb hidden in the back of a taxi was timed to injure as many people as possible, exploding during the lunchtime rush.

Less than five minutes later another bomb and more death. This time the target was the huge crowds of tourists at the Gateway of India monument.

The bomb turned one the country's most popular tourist spots into a scene of terror and devastation. The explosion was so powerful it shook buildings, blew people into the sea and shattered the windows at the Taj Mahal Hotel.

In Ottawa, a spokesman for Foreign Affairs said four Canadians were staying at the hotel, but none was injured.

Sargulam Noor, a guest at the hotel described the explosion. "Thank God I was not in the bedroom but I was in the main sitting-living room and I saw from there. Outside the bodies were lying, whether they were bodies or injured, but quite a few people were injured obviously, and I saw that this taxi's entire top was actually flown. It landed in front of the hotel here."

Hospitals struggled to cope with the wounded and officials made an emergency appeal for blood donations.

It is the worst terrorist attack in Mumbai in a decade, but many of the city's 16 million residents were on edge even before the explosions. There were several bomb attacks in the city earlier this year.

No one has claimed responsibility for Monday's attack. But officials say similar attacks in the past have been carried out by Islamic militants with ties to other militant groups backed by Pakistan.

Pakistan has condemned the bombings and called them "acts of terrorism."
