Snipers Kill Two; Serbs Shell Airport

Snipers killed two people Sunday in Sarajevo, including a man shot as he tried to rescue a wounded man, and Serb gunners renewed their attacks on the airport despite the threat of U.N. retaliation.

Violations of a 2 1/2-month-old truce have been increasing, and fighting between Muslim-led government troops and their Serb enemies is expected to flare with new intensity when the cease-fire expires May 1.

There were 744 truce violations in the Sarajevo area Saturday.
