JERUSALEM (Reuters) - Defense Minister Ehud Barak, signaling stronger Israeli military action against the Gaza Strip, said on Thursday militants would be made to pay a price for firing rockets toward Tel Aviv.

He also announced he had ordered the military to enlist more reservists "so that we can prepare for any development." The Israeli armed forces chief spokesman said the military had the green light to call in up to 30,000 reserve troops.

In remarks broadcast after rockets were fired at Tel Aviv, Barak said: "This escalation will exact a price that the other side will have to pay."
