Lebanese politicians are condemning Friday's bomb blast in a Christian neighborhood of Beirut as an attempt to sow sectarian strife in the formerly war-torn country.

In Beirut, a string of officials voiced their anger, while at the United Nations summit in New York, Prime Minister Fouad Siniora said the Lebanese people are resolute in preventing such attempts from destroying their spirit.

One person was killed and more than 20 others injured in the bomb blast late Friday, which took place on a residential street.

Lebanon has suffered a series of bombings since the massive explosion in February that killed former Prime Minister Rafik Hariri and 20 other people.

Syria is widely accused of involvement in his killing, and Friday's explosion comes days before U.N. investigator Detlev Mehlis is to return to Damascus to interview several Syrian officials about the assassination.
