ISLAMABAD, Pakistan (CNN) — A car bomb detonated Saturday night in the heart of Islamabad, killing at least 20 people and wounding at least another 20, police said.

The blast caused a natural gas leak that set the Marriott Hotel on fire, police said. More than a dozen cars were reduced to twisted steel.
Police described the blast, which occurred at 8 p.m. (10 a.m. ET), as a car bomb. Rescue workers pulled bloodied victims from vehicles.
The fifth floor of the hotel was ablaze and nearby trees were felled by the blast, which occurred hours after newly elected President Asif Ali Zardari addressed a joint session of Parliament and promised to root out terrorism.
Who is responsible? Al-Qaeda, Taliban, Jihadis, Jangi Junoonis (war maniacs), Sectarian groups, rogue elements in ISI and other intelligence agencies.
