An AP investigation found that smuggling is big in Gaza.

Israel restricts some goods.

Smuggling has grown a lot.

Palestinians pay high prices.

Hospitals buy medicine from smugglers.

The investigation used court papers.

It also used talks with traders, truckers, and officials.

Cigarettes and tobacco make the most money.

But smugglers also bring iPhones, solar panels, fuel, and anesthetics.

Israel stops or limits some goods.

It calls many of them "dual use" items.

Hamas militants could use them.

Smuggling rings make millions of dollars.

They pay Israeli troops, drivers, and warehouse workers.

These people work on both sides of the border.

Gaza's Hamas-led government also makes money.

It takes a part of smuggled goods.

Merchants call this "taxing."

Two big traders said they paid Hamas.

One paid $3.5 million.

The other paid $3.75 million.

Two senior Hamas officials said the money helps pay for services and salaries.

They think up to $100 million was collected since the ceasefire.

Israeli authorities broke up several smuggling rings.

They charged more than a dozen people.

Some of them were reserve soldiers.

In one case, a ring paid a commander about $120,000.

He put cigarettes in his vehicle.

For Gaza residents, prices are very high.

A vehicle battery costs over $2,300.

Before the war, it cost $140.

Fans cost $100 before.

Now they cost $500.
