JERUSALEM - (AP) -- Palestinian militants have fired a rocket toward Jerusalem, causing an explosion moments after air raid sirens sounded across the city.
The sound of Tuesday's blast could be heard in the distance from downtown Jerusalem.
Police spokesman Micky Rosenfeld said the rocket apparently did not reach the city and authorities are searching for the blast site.
It's the second rocket attack aimed at Jerusalem since a round of fighting broke out between Israel and Palestinian militants in Gaza last Wednesday. Jerusalem, nearly 80 kilometers (50 miles) from Gaza, is the most distant city the militants have targeted.
The rocket attack occurred as diplomats are trying to work out a cease-fire.
